(physics) The turning or bending of any wave, such as a light or sound wave, when it passes from one medium into another of different optical density.
A ray of light being refracted in a plastic block
(physics) The turning or bending of any wave, such as a light or sound wave, when it passes from one medium into another of different optical density.
Refraction of light at the interface between two media of different refractive indices, with n2 > n1. Since the phase velocity is lower in the second medium (v2 < v1), the angle of refraction θ2 is less than the angle of incidence θ1; that is, the ray in the higher-index medium is closer to the normal.
