At one particular angle for a given n1 and n2, the value of Rs goes to zero and an s-polarised incident ray is purely refracted. This is known as Brewster's angle. |

At one particular angle for a given n1 and n2, the value of Rp goes to zero and an p-polarised incident ray is purely refracted. This is known as Brewster's angle. When moving from a more dense medium into a less dense one (i.e. n1 > n2), above an incidence angle known as the critical angle all light is reflected and Rs=Rp=1. This phenomenon is known as total internal reflection. http://meta.wikipedia.com/upload/fresnel2.png |
