What is a rarefaction in waves?
A rarefaction is a region in a longitudinal wave where the particles are furthest apart. The region where the medium is compressed is known as compression and the region where the medium is spread out is known as a rarefaction.
What is a rarefaction easy definition?
Definitions of rarefaction. a decrease in the density of something. “a sound wave causes periodic rarefactions in its medium”
What is a rarefaction example?
If the prong of a tuning fork vibrates in the air, for example, the layer of air adjacent to the prong undergoes compression when the prong moves so as to squeeze the air molecules together. When the prong springs back in the opposite direction, however, it leaves an area of reduced air pressure. This is rarefaction.
Where is the rarefaction of the wave?
A rarefaction is the area of a wave (or Slinky) that is spread out. This is the wave’s trough. You can also think of a rarefaction in terms of density: The rarefaction is the part of the wave that has the lowest density.
What is refraction of a wave?
refraction, in physics, the change in direction of a wave passing from one medium to another caused by its change in speed. For example, waves travel faster in deep water than in shallow.
How rarefaction is formed?
When a vibrating object goes forward in air as medium it pushes and compresses the air. This is the compression. When a vibrating object goes back in air as medium it creates a region of low pressure. This is the rarefaction.

What causes refraction waves?
Wave refraction – Wave refraction causes wave fronts to parallel the shape of the coastline as they approach shore and encounter ground. Wave refraction causes wave energy to concentrate on headlands and preferentially erode them rather than bays.
What is an example of a refraction?
Glass is a perfect everyday example of light refraction. Looking through a glass jar will make an object look smaller and slightly lifted. If a slab of glass is placed over a document or piece of paper, then the words will look closer to the surface because of the different angle the light is bending.

What is the definition of wave refraction?
In physics, refraction is the redirection of a wave as it passes from one medium to another. The redirection can be caused by the wave’s change in speed or by a change in the medium.
What is the best definition of refraction?
: the bending of a ray when it passes at an angle from one medium into another in which its speed is different (as when light passes from air into water) refraction.
What causes refraction?
Refraction is caused due to the change in speed of light when it enters from one medium to another. When the light goes from air into water, it bends towards the normal because there is a reduction in its speed.

What is refraction kid friendly definition?
Refraction happens when light changes direction, or bends, when it moves from one material to another. For example, light traveling through the air refracts when it hits water. This can make a straw in a glass of water look bent at the surface of the water. Some surfaces neither reflect nor refract light.
What is a example of refraction?
A swimming pool always looks shallower than it really is because the light coming from the bottom of the pool bends at the surface due to refraction of light. Formation of a rainbow is an example of refraction as the sun rays bend through the raindrops resulting in the rainbow.
What is an example of refraction in waves?
Refraction occurs with any kind of wave. For example, water waves moving across deep water travel faster than those moving across shallow water. A light ray that passes through a glass prism is refracted or bent.

What is the bottom of a wave called?
The lowest part is called the trough. The wave height is the overall vertical change in height between the crest and the trough and distance between two successive crests (or troughs) is the length of the wave or wavelength.

What causes refraction in waves?
NARRATOR: Refraction is the change in direction of a wave as it passes from one medium to another. Refraction is caused by the wave’s change of speed.
