Question 191 of 191

The angle of incidence at which reflected light totally polarized for reflection from air to glass (refractive index nn ), is

Show answer and solution

Answer: (D) tan⁡−1(n)\tan ^{-1}(n)

Brewster's law: According to this law the ordinary light is completely polarised in the plane of incidence when it gets reflected from transparent medium at a particular angle known as the angle of polarisation.
n=tan⁡ip\mathrm{n}=\tan \mathrm{i}_{\mathrm{p}}
