Refraction of Light

120 - Refraction of Light

In this video Paul Andersen explains how light can be refracted, or bent, as it moves from one medium to another. The amount of refraction is determined by the angle of incidence and the index of refraction. Snell's Law can be used to calculate the angle of refraction. When the angle of incidence exceeds the critical angle it will result in total internal reflection.
