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.

It occurs when light hits a different matter then it was traveling in.

What is it called when a wave goes from one medium to another and it changes speed and direction?
The change in direction is called refraction.
What are the reflection refraction diffraction?
* 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.
Why refraction of a wave occurs when the wave travels from one material into another?
The change in wave speed causes refraction sinv1/v1 = sinv2/v2.
When a light wave enters into a medium of different optical density?
index of refraction ( or refractive index)
What is the bending of a light wave called?
It is called refraction
What is it called when a wave goes from one medium to another and it changes speed and direction?
The change in direction is called refraction.
What is it called when waves change there speed when they go in to different matereals?
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.
What is changed to cause refraction?
Refraction is a change in direction of a wave due to a change in its transmission medium.
What are 3 ways that waves change direction?
Three ways that waves change direction are reflection, refraction, and diffraction.

What wave property makes a straw look broken?
It is caused by refraction.
Which describes the change in the wave as it encounters the barriers?
Refraction.

index of refraction ( or refractive index)
What is the bending of a light wave called?
It is called refraction
When waves bounce back off of another surface it is called?
Reflection or refraction if the wave scatters.
How does refraction cause wave crests to move when the waves approach the shore?
nearly parallel to the shoreline
