Diagram showing the refraction (or bending) of a ray of light as it passes from a medium of lower optical density, to a medium of higher optical density, for example when it passes from air into water or glass. Refraction is the change in direction of propagation of a wave (in this case light) that occurs when the wave passes from one medium to another with a different density. As light passes through the block it slows down and is refracted towards the perpendicular ormal"" line, due to the greater density of the glass. The greater the angle of incidence (i), the greater the amount of refraction." | |
