light is bent. If you put a straight rod into water, the light in the water makes it look like it's smaller and slightly bent.
Waves change direction when they move from one medium to another and the speed of the wave is different in each.
This answer is false. Refraction does not occur when a wave strikes an object and bounces off. This is what is known as reflection.
nearshore part of the wave is slowed.
The amplitude changes
speed
It occurs when light hits a different matter then it was traveling in.
The change in direction is called refraction.
* Refraction occurs when a wave crosses a boundary from one medium to another. A wave entering a medium at an angle will change direction. * Diffraction refers to the "bending of waves around an edge" of an object. Diffraction depends on the size of the object relative to the wavelength of the wave. * Reflection:Waves can and do meet boundaries in their medium. When a wave meets a boundary, it can be reflected or transmitted. Reflection can be partial or complete. Reflection can also involve a phase flip (change of phase of 180 degrees.) * All these phenomena apply to electromagnetic waves, such as light waves, as well as to pressure waves and water waves.
The change in wave speed causes refraction sinv1/v1 = sinv2/v2.
index of refraction ( or refractive index)
It is called refraction
The change in direction is called refraction.
This is related to a change in direction. The change in direction is called refraction. The numbers that describe HOW MUCH the speed of the wave slows down is called "index of refraction", especially in the case of light waves.
Refraction is a change in direction of a wave due to a change in its transmission medium.
Three ways that waves change direction are reflection, refraction, and diffraction.

It is caused by refraction.
Refraction.
index of refraction ( or refractive index)
It is called refraction
Reflection or refraction if the wave scatters.
