Comments |
At an interface between two media, refractive indices n1 and n2 , Brewster's Law states that at a certain angle, the refracted beam will be polarised perpendicular to the plane of incidence. If the incoming beam's E field is in the incident plane, then at the Brewster angle, no reflection will be observed. |
