Brewster's Angle

Brewster's angle is an angle of incidence at which light with a particular polarization is perfectly transmitted through a transparent dielectric surface, with no reflection.

The tangent of Brewster's angle equals the ratio of the indices of refraction.

Formula

Tan[QuantityVariable[Subscript["θ", "B"], "Angle"]] == QuantityVariable[Subscript["n", "2"], "Unitless"]/QuantityVariable[Subscript["n", "1"], "Unitless"]

symbol description physical quantity
θB Brewster's angle "Angle"
n1 index of refraction (first medium) "Unitless"
n2 index of refraction (second medium) "Unitless"
