The degree to which this phenomenon polarizes light is called Brewster's Angle, and Fresnel's equations and Huygens' principle govern this process. When a wave passes through an anisotropic material and decomposes into two waves, birefringence, the double version of this phenomenon, occurs. Snell's law relates the angle of incidence with the index 
The degree to which this phenomenon polarizes light is called Brewster's Angle, and Fresnel's equations and Huygens' principle govern this process. When a wave passes through an anisotropic material and decomposes into two waves, birefringence, the double version of this phenomenon, occurs. Snell's law relates the angle of incidence with the index of this process. The separation of white light into a rainbow as it passes through a prism is an example of this phenomenon. For 10 points, name this bending of a wave as it passes through a new medium.
