Refraction - Wikipedia, the free encyclopedia

Refraction is the change in direction of a wave due to a change in its velocity. This is most commonly observed when a wave passes from one medium to another. Refraction of light is the most commonly...

Ray Optics, Light Refraction ... Refraction occurs when a light ray changes mediums. Light traveling from air and going into water would be an example. The speed of the light ray changes upon changing mediums. In almost every case the direction of the light ray changes also.

Refractive index - Wikipedia, the free encyclopedia

The refractive index (or index of refraction ) of a medium is a measure of how much the speed of light (or other waves such as sound waves) is reduced inside the medium. For example, typical soda-...
en.wikipedia.org/wiki/Refractive_index
Refraction is the bending of a wave when it enters a medium where it's speed is different. The refraction of light when it passes from a fast medium to a slow medium bends the light ray toward the normal to the boundary between the two media.

This java applet is a simulation of a ripple tank. Here, it is demonstrating refraction. A series of wave packets are emitted from the upper left. These waves are reflected and refracted by the blue medium, which has a higher refractive index than the gray medium.
