Physics. the change of direction of a ray of light, sound, heat, or the like, in passing obliquely from one medium into another in which its wave velocity is different.
Refraction is the change in direction of propagation of a wave due to a change in
its transmission medium. The phenomenon is explained by the conservation of ...
Refraction is the bending of a wave when it enters a medium where its speed is
different. The refraction of light when it passes from a fast medium to a slow ...

Definition: (DOD) The process by which the direction of a wave is changed when moving into shallow water at an angle to the bathymetric contours. The crest of the wave advancing in shallower water moves more slowly than the crest still advancing in deeper water, causin... More »
This optical effect is due to refraction. As light passes from one transparent
medium to another, it changes speed, and bends. How much this happens
For people over age 40 who have normal distance vision but difficulty with near
vision, a refraction test can determine the right power of reading glasses.
Willebrord Snel (1580–1626) Netherlands. "Although he discovered the law of
refraction, a basis of modern geometric optics, in 1621, he did not publish it and ...
In this free online math game, students explore various concepts related to
fractions as they reflect light in space.
