Brewster's angle

Brewster's angle, also known as the polarization angle, is the angle of incidence at which light with a particular polarization is perfectly transmitted through a transparent dielectric surface, with no reflection. At this angle, the reflected light is completely polarized perpendicular to the plane of incidence. Mathematically, Brewster's angle (θ_B) can be determined using the refractive indices of the two media involved.
