Angle of refraction
A measure of the change in direction that occurs when a light ray passes through an interface between two mediums with different densities. This change in direction is called refraction*. The angle of refraction is the angle between the transmitted light ray and a line normal* to the surface the ray transmits through. The incident angle and the difference in density* between the two media determine the angle of refraction.
