Waves on the surface of water HD
 
00:58
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.

Types of Sound waves physics
 
03:32
Types of Sound waves physics Sound is a form of energy. Sound is that form of energy which makes us here. Sound travels in the form of waves A wave is a vibratory disturbance in a medium which carries energy from one point to another without there being a direct contact between two points. Example If we throw a piece of stone industrial surface of water in a pond, then expanding circles called ripples or water waves are formed over the surface of water when a water wave passes over the surface of water in a pond, full moment of water from the centre to the sides of the pond, only the water molecules vibrate up and down about their fixed position. A waveis produced by the vibration of the particles of the median through which it passes. example When sound waves produced by a ring Bell through air then there is no actual movement of the air from the bell only sound energy Travels through the vibration of molecules similarly water waves passes. There are two types of waves Longitudinal waves Transverse waves A wave in which the particles of the medium vibrate back and forth in the same direction in which the wave is moving, call a longitudinal wave. Diagram Longitudinal waves can be produced in all the three media: solids liquids and gases. Example The waves which travel along a spring( or slinky) when it is pushed and pulled that one end, are longitudinal waves. Diagram The Waves produced in air when a guitar wire( sitar wire, tanpura tanpura wire or violin wire) is plucked are longitudinal waves. Longitudinal wave consist of compressions and rarefactions travelling through medium. Transverse waves A wave in which the particles of the medium vibrate up and down 'at right angles' to the direction in which the wave is moving, is called a transverse wave.

GCSE Physics - Water Waves - Shallow to Deep Water
 
05:32
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.

Making standing waves
 
04:43
A standing wave is made by sending a wave group down the tank against a fixed wall. The reflected wave will superimpose upon the incident waves doubling the amplitude. As the wave maker imparts more energy in to the system, the amplitude increases. The waves are sustained by gravity and hydrostatic force and dissipated by fluid viscosity (the frictional forces against the wall are negligible). The video has been edited as the clopotis and seiche that occur last over a half hour and are eventually killed with the wave maker acting as an absorber, as it tries to produce waves offset by one half period of the waves hitting it.

The Original Double Slit Experiment
 
07:40
Light is so common that we rarely think about what it really is. But just over two hundred years ago, a groundbreaking experiment answered the question that had occupied physicists for centuries. Is light made up of waves or particles? The experiment was conducted by Thomas Young and is known as Young's Double Slit Experiment. This famous experiment is actually a simplification of a series of experiments on light conducted by Young. In a completely darkened room, Young allowed a thin beam of sunlight to pass through an aperture on his window and onto two narrow, closely spaced openings (the double slit). This sunlight then cast a shadow onto the wall behind the apparatus. Young found that the light diffracted as it passed through the slits, and then interfered with itself, created a series of light and dark spots. Since the sunlight consists of all colours of the rainbow, these colours were also visible in the projected spots. Young concluded that light consist of waves and not particles since only waves were known to diffract and interfere in exactly the manner that light did in his experiment. The way I have always seen this experiment performed is with a laser and a manufactured double slit but since the experiment was conducted in 1801 I have always thought that it should be possible to recreate the experiment using sunlight and household materials. That is basically what I did here. I will show the interference pattern I observed with my homemade double slit on 2Veritasium but I chose to use a manufactured double slit here to ensure that the pattern was impressive for observers at the beach. Special thanks to Henry, Brady, and Rupert for their cameos, Glen for filming and Josh for helping create the apparatus. Thanks also to the Royal Society for allowing us to view the original manuscript of Young's lecture and the University of Sydney for lending the double slits.

Wave behaviour | Waves | Physics for All | FuseSchool

How do waves behave? Badly? In this video we are going to look at how light and sound waves behave. Before we start, you should know that waves can be transverse or longitudinal. Transmission, reflection, refraction, diffraction, absorption and scattering are all typical wave behaviours. Reflection is when waves bounce off an object. Sound waves are reflected by hard, flat surfaces and is why we get echoes. You hear a delay between the original sound and the echo, because the echoed sound waves have to travel twice as far to reach your ears. Smooth surfaces, like glass and polished metal, reflect light in a regular way, so a reflection can be seen. Like a mirror, or seeing your face in a calm pond. Transmission is when waves keep travelling in the same direction through an object. Like light through a window. Absorption and reflection often go hand in hand for light waves. White light contains each wavelength - so all the colours of visible light. The colour of an object depends on which wavelengths of light it absorbs and which it reflects. White objects reflect all the light that hits them, and absorbs none. Black objects reflect none and instead absorb all the light that hits them. A red object absorbs all the wavelengths except the red, which is reflected. And a green object absorbs all the wavelengths except the green, which is reflected. Are the new people upstairs really noisy? If they carpet their floors, add curtains and furniture to the room then you’ll notice that they become much quieter. This is because some objects absorb sound waves. When sound and light waves pass across a boundary between two substances, like air and glass, they change speed. This is because the substances have different densities. The change is speed causes the waves to change direction, which is known as refraction. Because of refraction, things in water look closer than they really are and water appears shallower than it really is. And a straw in a glass of water looks like it bends at the surface, because the refracted light wavelengths make you think the straw is in a different place to where it actually is. When waves meet a gap in a barrier, they pass through the gap. They then spread back out after they pass through the gap - this is diffraction. The way the waves re-spread depends upon how big the gap is compared to the incoming wavelengths. We have diffraction to thank for loudspeakers. Sometimes waves depart from the expected path, and spread out in multiple directions. This is known as scattering. We have scattering to thank for making the sky appear to be blue. The white light coming from the sun hits the molecules in our atmosphere, which cause the shorter blue wavelengths to scatter out in all directions. So waves behave in a variety of ways, depending upon what material they hit.

All waves can transfer energy from one place to another without transferring any matter. This is done by a series of disturbances or vibrations that carry the energy. Just like the people in their seats, only moving up and down when it’s their turn. Waves can transfer energy through solids, liquids, gases and empty spaces – otherwise known as vacuums. There are two types of waves – which we will look at in more detail in another video, but the basic features are the same. The frequency of a wave is the number of complete waves passing a fixed point in a given amount of time. This time period is usually one second. Frequency is given the symbol f and is measured in units called Hertz. Hertz measure how many complete cycles per second; so how many people in our Mexican wave stand up every second. The frequency and period are often confused. The frequency refers to how often something happens, whereas the period refers to the time it takes to happen. The period of a wave is the time for one complete cycle. So the time taken for one person to stand up, wave and sit down. This would be measured in seconds. When something happens repeatedly we say that the event is periodic and refer to the time for the event to repeat itself. The period of the earth to orbit the sun is 365 days, the period of a day is 24 hours, the period of a typical class at school is 45 minutes. Now for the wavelength… the wavelength is the distance between a point on one wave and the same point on the next wave, for example two peaks or two troughs. Wavelength is given the symbol Lambda from the Greek letter, and is usually measured in metres. Wavelengths can vary hugely in size, x-rays are very short, visible light is here and FM radiowaves are much longer. So we’ve looked at the frequency, period and wavelength so far. Let’s finish with amplitude. As waves travel, they create disturbance. The amplitude of a wave is the distance from the maximum disturbance to its undisturbed position. Think of a very flat sea… and then an incoming wave. The amplitude is the height of the top of the wave from the flat sea. In another video we’ll be looking at the wave speed equation, and connecting wavelengths and frequencies: Wave Equation For now you just need to know what these 4 keys words mean.

Waves : Introduction and Types of Waves : Class 11 Physics
 
14:04
This is just a demo video, for more videos and full syllabus please contact us on 8287971571 or 0261-4890014. Waves: Introduction and Types of Wave (Chapter 15): Class 11 Physics. Here we discuss mainly Waves and types of waves of chapter 15 from class 11 physics. Let's start with, What is Wave? Wave is a disturbance which carries energy from one location to another without the flow of mass. Wave is also known as a transverse wave. Transverse wave, motion in which all points on a wave oscillate along paths at right angles to the direction of the wave’s advance. Surface ripples on water, seismic S (secondary) waves, and electromagnetic (e.g., radio and light) waves are examples of transverse waves. Types of Waves There are mainly 2 (two) types of waves. 1) Electromagnetic waves 2) Mechanical waves Electromagnetic waves: Electromagnetic waves are waves that can travel even through a vacuum. For example Light Mechanical waves: Mechanical waves can’t flow through a vacuum. They need a medium to travel. For example Sound Mechanical waves further divide into 2 (two) parts. 1) Transverse waves 2) Longitudinal waves All the above-mentioned topics are described in an interactive and efficient manner so that the students could easily understand them.

Interference of waves in a ripple tank
 
01:55
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.

What is TRANSVERSE WAVE? What does TRANSVERSE WAVE mean? TRANSVERSE WAVE meaning & explanation

What is TRANSVERSE WAVE? What does TRANSVERSE WAVE mean? TRANSVERSE WAVE meaning - TRANSVERSE WAVE definition - TRANSVERSE WAVE explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. A transverse wave is a moving wave that consists of oscillations occurring perpendicular (or right angled) to the direction of energy transfer. If a transverse wave is moving in the positive x-direction, its oscillations are in up and down directions that lie in the y–z plane. Light is an example of a transverse wave. With regard to transverse waves in matter, the displacement of the medium is perpendicular to the direction of propagation of the wave. A ripple in a pond and a wave on a string are easily visualized as transverse waves. Transverse waves are waves that are oscillating perpendicularly to the direction of propagation. If you anchor one end of a ribbon or string and hold the other end in your hand, you can create transverse waves by moving your hand up and down. Notice though, that you can also launch waves by moving your hand side-to-side. This is an important point. There are two independent directions in which wave motion can occur. In this case, these motions are the y and z directions mentioned above, while the wave propagates away in the x direction. Continuing with the string example, if you carefully move your hand in a clockwise circle, you will launch waves in the form of a left-handed helix as they propagate away. Similarly, if you move your hand in a counter-clockwise circle, a right-handed helix will form. These phenomena of simultaneous motion in two directions go beyond the kinds of waves you can create on the surface of water; in general a wave on a string can be two-dimensional. Two-dimensional transverse waves exhibit a phenomenon called polarization. A wave produced by moving your hand in a line, up and down for instance, is a linearly polarized wave, a special case. A wave produced by moving your hand in a circle is a circularly polarized wave, another special case. If your motion is not strictly in a line or a circle your hand will describe an ellipse and the wave will be elliptically polarized. Electromagnetic waves behave in this same way, although it is slightly harder to see. Electromagnetic waves are also two-dimensional transverse waves. Ray theory does not describe phenomena such as interference and diffraction, which require wave theory (involving the phase of the wave). You can think of a ray of light, in optics, as an idealized narrow beam of electromagnetic radiation. Rays are used to model the propagation of light through an optical system, by dividing the real light field up into discrete rays that can be computationally propagated through the system by the techniques of ray tracing. A light ray is a line or curve that is perpendicular to the light's wavefronts (and is therefore collinear with the wave vector). Light rays bend at the interface between two dissimilar media and may be curved in a medium in which the refractive index changes. Geometric optics describes how rays propagate through an optical system. This two-dimensional nature should not be confused with the two components of an electromagnetic wave, the electric and magnetic field components, which are shown in the electromagnetic wave diagram here. The light wave diagram shows linear polarization. Each of these fields, the electric and the magnetic, exhibits two-dimensional transverse wave behavior, just like the waves on a string. The transverse plane wave animation shown is also an example of linear polarization. The wave shown could occur on a water surface.

Find my revision workbooks here: https://www.freesciencelessons.co.uk/workbooks/shop/ In this video, we look at refraction of waves. First we explore what is meant by refraction and look at how this is due to changes in the speed of waves as they change from one medium to another. Finally, we use the idea of wavefronts to explain how changes in wave speed cause refraction.
