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

n

), is

Options

A $\sin ^{-1}(n)$
B $\sin ^{-1}(1 / n)$
C $\tan ^{-1}(1 / n)$
D $\tan ^{-1}(n)$

Correct answer

D. $\tan ^{-1}(n)$

Step-by-step solution

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.

\mathrm{n}=\tan \mathrm{i}_{\mathrm{p}}
