Question

Explain polarization by reflection ( BREWESTER LAW)

Answer 1

Brewster Law states that the tangent of the polarizing angle of incidence (i.e, the Brewster angle) of a transparent medium is equal to the refractive index of the medium.

i.e., μ = tan ip

where ip = polarizing angle of incidence (p is in subscript) = Brewster angle
and,μ = refractive index of the transparent medium

Answer 2

Brewester angle (also known as polarization angle ) is an angle of incidence at which light with a particular polarization is perfectly transmitted through a transparent dielectric surface , with no reflection .
