This tutorial is about how waves can speed up or slow down when then enter a material with a different optical density, or when water waves enter regions of different depths. This change of velocity can cause the waves to change direction - this is called REFRACTION. Subscribe for more physics tutorials like this: http://bit.ly/Subscribe-Physics-Ninja Water waves will refract when then move from shallow to deep water causing them to speed up. As a result, their wavelength will increase and the refracted ray will 'SPEED AWAY' from the normal line. Remember that the wavefronts are always at 90 degrees to the ray. Use 'RNAR' to work through the steps: 1. Ray (incident ray) 2. Normal (line perpendicular to surface where the ray enters) 3. Angles (label the angle of incident and angle of refraction) 4. Use the refraction rule "SPEED AWAY" to determine which direction the refracted ray will bend. Quick question: During refraction, the wavelength and the speed of the wave changes. What does NOT change about the wave? (Answer... the frequency of the wave does not change) So why do waves get faster in deeper water? The answer is a bit complex, but here is an explanation posted at the Illinois Department of Physics: 1. For a shallow fluid, the motion of the fluid is mostly side-to-side. 2. In order to accumulate more fluid in one place (to make the crest of the wave), each little bit of fluid must travel a little farther than it would have to in deeper water. 3. When a wave passes, the bits of fluid (if you could watch one at a time) travel in ellipses. For shallow water, the ellipses are stretched out horizontally, and in very deep water, they are very nearly circular. 4. So for a wave of the same height (top to bottom of the ellipse), the bits of water must travel farther in the shallow tray than the deep tray. 5. Because the waves of the same height in shallow and deep water exert the same pressure differences due to gravity to get the water moving (although the motion is different due to the fact that the bottom is there), similar forces push and pull on the water. 6. To get the water moving farther and faster with the same force takes a longer time for each push, and hence a slower speed for the wave which travels in the shallow water.

Interference of Waves | Interference and superposition explained in light and water waves with animation | Interference of waves in two dimensions | Physics The phenomena of the light which undergoes refraction and reflection by be explained by the 2 theories of light. They are corpuscular and wave theory of light. But some of the other phenomena such as interference and diffraction can only be explained by wave theory of light. We know that 2 or more wave, motions travel in space at the same time. Sometimes these 2 wave motions combine to and some physical effects take place. Inference is once such physical effect. When 2 or more waves cross each other in the same medium, they both interfere and accident takes. This accident is known as interference of waves. Interference is the combine effect of the disturbance caused by the each individual wave at the same place and at same time. This effect can be understood from the principle of superposition of waves. Principle Of superposition of waves: To understand this concept of the superposition, let's understand some of the examples. When we drop a pin in a tank, we see some circular waves. When other another pin is dropped, we see some more waves. These waves travel in the same tank and some or the other time these superimpose on each other. The resultant wave would have amplitude which is the sum of the displacement due to the individual waves. " The principle of superposition of waves states that when two or more waves travel through the same medium simultaneously, the resultant displacement at any point is the vector sum if the displacement due to the individual waves." In our case the pin is dropped in a ripple tank with 2 pins. If Y1 is the displacement caused at a point due to the first source and Y2 is the displace cause by the 2nd source, then the over displacement R at the point of interference would given by R=Y1+Y2 When both the sources have the same amplitude which then Y1,Y 2 would be equal to Y. When Y1 is due the crest or trough and Y2 is also due a crest or trough the resultant would be the maximum and when Y1 is due to a crest and Y2 is due to a trough or vice versa, the displacement would be minimum. When maximum displacement takes place it's called constructive superposition and when minimum displacement takes place it's called the destructive superposition. In constructive displacement, a maximum displacement curve is produced. Thus, when constructive displacement occurs then the phase difference between the waves would be ZERO or a multiple of 2π. When minimum displacement occurs, wave super impose destructively, the phase difference of the waves would be π or an odd integral multiple of the π. Interference of waves: When superposition of waves occurs, they could be constructive or destructive. This physical effort observed as a result of the superposition of waves is called interference. "The physical effect of the superposition of waves from the sources vibrating with the same frequency and amplitude is called the interference of waves. The physical effect is in the form of vibrations in the amplitude of resultant wave in a given potion of the medium" Interference is a special case of superposition of waves which originate from different sources but have the same amplitude, same frequency.

An experiment to show the interference of waves in a ripple tank using a shallow depth of water two point circle waves are generated. Where the two crests meet they are amplified giving constructive interference and where a crest and a trough meet there is destructive interference and no wave is produced. this experiment is done as part of GCSE physics showing a property of diffraction.

http://www.sciencetutorial4u.com THE BASIC OF WAVES # Waves can only transfer energy but not matters. # Wavelength is the distance from the crest to crest or trough to trough. # Amplitude is half the height of the wave. # Frequency is the number of wave cycles passing in a second (one second). # The unit of frequency is Hertz which is Hz. # If frequency increases, wavelength decreases and vice versa (which means wavelength and frequency have opposite relationship). # The amplitude determines the loudness in a wave sound.

A simple yet affective way to show wave superposition. When the high parts of the wave (crests) are lined up, the resulting wave is larger in amplitude. When a high part and a low part (trough) meet, the result is a wave of zero amplitude, or a straight line.

One plus one equals two. That is true in understanding how one wave crest interact with another wave crest of the same phase, which in common terms is in sync. When out of sync, such as one wave crest meeting a wave trough, one plus negative one equal zero. This is the essence of constructive and destructive interference in wave dynamics. Understandable when presented as in above, what is difficult is in understanding how two or more wave propagations interact at specific points of space in their interference zone. The tool to do this is Huygens’ construction, but although graphical in nature, it is a major bugbear of most students in understanding wave dynamics. Because students could not visualize the cross interaction lines on their Huygens’ construction, and determine which nodes are constructive interference and where are the destructive ones. The intellectual leap needed to overcome the last point is crucial to understanding wave dynamics and using it to solve problems in hydraulics, design of breakwater location, and how earthquake waves move through earth. The four videos in this series features waves associated with high tide coming to shore at Labrador Park, Singapore that manifest in clear constructive and destructive interference zones. Waves breaking up into foamy water as it nears shallow land can also be observed. Hopefully, the videos would be useful for students to visualize wave dynamics and researchers seeking to understand the hydrology of Labrador Park in Singapore.

#iitutor #Physics #TheWorldCommunicates https://www.iitutor.com The wavelength of a transverse wave is the distance between successive crests or troughs measured in the direction of the wave's velocity. Notice that the shape of the wave is repeated or periodic. Each repeated shape represents one complete cycle of the wave. A wavelength is the length of one complete cycle of the wave in the direction of the wave's propagation. For a longitudinal wave, the wavelength is the distance between successive compressions or rarefactions. The amplitude of a wave is defined as the maximum displacement of the medium from its equilibrium position. For a transverse wave, the amplitude is half the distance between a crest and a trough, measured perpendicular to the direction of travel. The amplitude of a sound wave determines the volume (loudness) of the sound, while the amplitude of a light wave determines the brightness of the light. The period of a wave is the time required for one complete cycle of the disturbance. It is also the time for one wavelength to pass a fixed point in the medium, or the time for any point in the medium to complete one whole cycle of the motion it executes as the wave passes. The number of complete cycles that pass a stationary observer per second is called the frequency of the wave. Frequency is measured in cycles per second or hertz (Hz). The period is related to the frequency because the time for one cycle in seconds must be one second divided by the number of cycles per second. For example, if there were five cycles per second the time for one cycle would be 1/5th of a second. The pitch of a sound wave is determined by the sound's frequency. The musical note called middle C has a frequency of 256 Hz, while high C corresponds to a frequency of 512 Hz. The sensation we experience as colour is determined by the frequency of the light waves that enter our eyes. The energy carried per second through an area of one square metre perpendicular to the wave's velocity is called the wave's intensity. The intensity of the wave is a measure of the energy carried by the wave through the medium. The SI units of intensity are watts per square metre. The wave velocity is the speed at which the disturbance moves through a material. It depends on several things: • the kind of wave • the type of material-its density (e.g. are the particles closely packed?). The velocity (v) of a wave depends on its frequency or wavelength, not on the amplitude of the wave. For any given wave the frequency is fixed by the source frequency and the velocity is fixed by the material through which it travels. The frequency and wavelength are related in the following way by the wave equation. The wave motion we have discussed so far is that in which the wave is confined to a string, spring or pipe. If we drop a stone into a pond, the ripples spread out in all directions from the impact point. The ripples are initially circular. If we let off a fire cracker, the blast wave begins to move outward as a spherical pulse. With time, the ideal shape of the front of the disturbance is distorted by intervening objects, and by other disturbances. In each case the waves start in a small group of particles that transfer their vibrational energy to their immediate neighbours. These neighbours pass on the vibration to other particles further from the source of the disturbance. In order to visualise the way in which the disturbance progresses outward it is useful to introduce the idea of a wavefront. At any given time we can join up all of the wave crests, which started from the source at the same time, as a wavefront. Wavefronts that originate from a single point source are usually spherical if they propagate through a volume or circular when they move across a membrane or surface (such as a water-air interface). We can represent the direction in which the wavefront is moving by arrows or rays, drawn at right angles to the wavefront. If we follow one set of arrows from the source outward we may join them to represent a ray. This graph can tell us a lot. For transverse waves the meaning of the displacement axis is obvious. It represents the displacement of particles perpendicular to the energy’s direction. However for longitudinal waves the actual displacement is in the direction of propagation of the wave and the up-or-down direction now represents the displacement from rest. The horizontal axis can he interpreted either as a space (distance) axis, or as a time axis. As the wave progresses, the different points on the wave (such as point X) are affected by the wave. If we consider the zero of time to occur at the instant shown, then it follows that point X will remain at rest for another second (the wave has to travel 1 cm at 1 cm/s and so takes 1 s to do so). It will then move down so that after a further 5 s its displacement will be -1.0 unit.

This video is on waves specifically waves on a string. Link of previous wave lecture - https://youtu.be/p1NhMSki_Bs A vibration in a string is a wave. Resonance causes a vibrating string to produce a sound with constant frequency, i.e. constant pitch. If the length or tension of the string is correctly adjusted, the sound produced is a musical tone. Constructive interference occurs whenever waves come together so that they are in phase with each other. This means that their oscillations at a given point are in the same direction, the resulting amplitude at that point being much larger than the amplitude of an individual wave. Destructive interference- In physics, interference is a phenomenon in which two waves superpose to form a resultant wave of greater, lower, or the same amplitude. When studying waves, it is helpful to use a string to observe the physical properties of waves visually. Imagine you are holding one end of a string, and the other end is secured and the string is pulled tight. Now, if you were to flick the string either up and down. The wave that occurs due to this motion is called a transverse wave. A transverse wave is defined as a wave where the movement of the particles of the medium is perpendicular to the direction of the propagation of the wave. Figure 1 shows this in a diagram. In this case, the medium through which the waves propagate is the rope. The wave traveled from one end to the other, while the rope moved up and down. Wave Properties Transverse waves have what are called peaks and troughs. The peak is the crest, or top point of the wave and the trough is the valley or bottom point of the wave. Refer to Figure 2 for a visual representation of these terms.The amplitude is the maximum displacement of a particle from its equilibrium position.Wavelength, usually denoted with a lambda (λ) and measured in meters, is the distance from either one peak to the next peak, or one trough to the next trough.Period, usually denoted as T and measured in seconds, is the time it takes for two successive peaks, or one wavelength, to pass through a fixed point.Frequency, f, is the number of wavelengths that pass through a given point in 1 second. Frequency is measured by taking the reciprocal of a period.

#iitutor #Physics #WorldCommunicates https://www.iitutor.com The development of our civilisation would have been impossible without effective communication. The early development of speech and later the written word allowed us to evolve a cohesive community that was capable of passing ideas and beliefs from generation to generation. The messenger carrying the information has been supplanted by electromagnetic means of transmission that allow transfer of data at close to the speed of light. To all intents and purposes, the sending and receiving of data over satellite links is instantaneous, limited only by the speed of coding and decoding the information into suitable forms for transmission. Speech and many modern means of communication utilise waves. There are many different kinds of waves. The most obvious form of waves are those upon which we surf. Less obvious are sound waves, and possibly the least obvious are light or electromagnetic waves. In this section we discuss what waves really are, and their importance in the world around us. All waves share one thing in common, they provide a means of transferring energy from one point to another without the physical movement of particles from one point to another. Ocean waves are generated thousands of kilometres out to sea by the action of wind on the surface of the ocean. The energy transferred to the surface of the ocean eventually reaches land a few days later as a breaking wave. However, the water molecules that were originally moved by the wind far out at sea do not move far from their original positions. They pass on their energy to neighbouring molecules, which in turn affect their neighbours. In this way energy is transferred without mass motion. If you put energy into a string or rope by shaking one end up and down, the other end of the string will also begin to move up and down. Energy will have been transferred along the string, but the molecules of the string will not have moved from their original relative positions. In a similar way electromagnetic radiation (which includes light) can be thought of as the transfer of energy from one place to another by varying electrostatic and magnetic fields. If you could take hold of an electron in one corner of the room and shake it up and down, you would find that other electrons at the other side of the room would begin to vibrate a split second later. Energy is transferred from one side of the room to the other by an electromagnetic wave. If particles and molecules don't actually move from one place to another when energy is transferred by a wave, what actually happens to the individual particles? Let's consider what happens if we drop a rock into a pool. Ripples spread out from the position where the rock entered the pool and eventually reach the pool's edge. Floating twigs and straw near the centre of the pool are not washed ashore, instead they begin moving up and down about an equilibrium point. Their vertical motion is a form of simple harmonic motion. This vertical oscillation is transferred outward from one region of the pool to the next. As the oscillation builds up in one area it dies away in the preceding area. The wave is seen to travel out from the pool's centre. Waves travel through the medium carrying energy only: they do not take any part of the medium with them. They cause an oscillation of the particles in the medium as they pass, but every particle returns to its equilibrium position after each complete cycle of the wave. In this way the particles of the medium transmit the wave but do not move along with it, and we can think of the wave as energy moving through the medium. Waves are disturbances that transfer energy from one point in a medium to another point. They may propagate in one, two or three dimensions depending on the type of wave and the medium through which it is moving. The best way to understand how waves are formed and how they travel is to consider a single pulse or wave hump. We can make such a pulse on a horizontal string resting on a table by rapidly flicking one end of the string up then down. As your hand pulls the end of the string up, adjacent pieces of the string feel a force that also accelerates them in a vertical direction. They in turn affect neighbouring pieces of string. As each succeeding piece of string moves upward, the crest of the pulse moves along the string. By now your hand has returned to its starting position and the end of the string has also returned to its original position. As adjacent pieces of string reach the top of their motion they experience a force pulling them back toward their starting positions. The source of the pulse is the motion of your hand, and the pulse is transferred down the string because of cohesive forces (tension) between the particles of the string.

When two light waves superpose with each other in such away that the crest of one wave falls on the crest of the second wave, and trough of one wave falls on the trough of the second wave, then the resultant wave has larger amplitude and it is called constructive interference.

The waves on the surface of the water are neither longitudinal nor transverse. We can see in animation that red ball, which simulates the molecule of the water surface, moves in a circle path. So, the wave on the water surface is the superposition of transverse and longitudinal motions of the molecules. The molecules on the water surface move under the action of surface tension and gravity. Next animation simulates the wave motion of the molecules in the surface layer of water (or other liquid). If the amplitude of this wave is small, then every molecule moves in a circle path. The radii of these circles are diminishing with depth, so the balls in bottom part of animation are still.

This is a follow-on from my previous video, with waves switched on. I am using a vertex shader in Godot to move the waves, and have a duplicate function in the main code which can determine wave height at a location. This is a big bodge at the moment, I'm not sure how I will combine the wave motion with the physics. In theory the waves should push and pull the boats up and down using impulses, but this is a bit finicky, so for a hack here I'm actually directly adding the wave height to the boats when rendered. The physics simulation is all occurring on a flat ocean! :) It should be better if I can get it all to work correctly through physics though, as the motion will be more realistic.

Quantum mechanics is the branch of physics relating to the very small. It results in what may appear to be some very strange conclusions about the physical world. At the scale of atoms and electrons, many of the equations of classical mechanics, which describe how things move at everyday sizes and speeds, cease to be useful. In classical mechanics, objects exist in a specific place at a specific time. However, in quantum mechanics, objects instead exist in a haze of probability; they have a certain chance of being at point A, another chance of being at point B and so on. Three revolutionary principles Quantum mechanics (QM) developed over many decades, beginning as a set of controversial mathematical explanations of experiments that the math of classical mechanics could not explain. It began at the turn of the 20th century, around the same time that Albert Einstein published his theory of relativity, a separate mathematical revolution in physics that describes the motion of things at high speeds. Unlike relativity, however, the origins of QM cannot be attributed to any one scientist. Rather, multiple scientists contributed to a foundation of three revolutionary principles that gradually gained acceptance and experimental verification between 1900 and 1930. They are: Quantized properties: Certain properties, such as position, speed and color, can sometimes only occur in specific, set amounts, much like a dial that "clicks" from number to number. This challenged a fundamental assumption of classical mechanics, which said that such properties should exist on a smooth, continuous spectrum. To describe the idea that some properties "clicked" like a dial with specific settings, scientists coined the word "quantized." Particles of light: Light can sometimes behave as a particle. This was initially met with harsh criticism, as it ran contrary to 200 years of experiments showing that light behaved as a wave; much like ripples on the surface of a calm lake. Light behaves similarly in that it bounces off walls and bends around corners, and that the crests and troughs of the wave can add up or cancel out. Added wave crests result in brighter light, while waves that cancel out produce darkness. A light source can be thought of as a ball on a stick being rhythmically dipped in the center of a lake. The color emitted corresponds to the distance between the crests, which is determined by the speed of the ball's rhythm. Waves of matter: Matter can also behave as a wave. This ran counter to the roughly 30 years of experiments showing that matter (such as electrons) exists as particles.
