A parallel beam of monochromatic unpolarised
light is incident on a transparent plate of
refractive index

\sqrt{3}.

The reflected beam is
completely polarized. The angle of incidence
is

View answer and explanation

Correct option: B

60^\circ

Option B (

60^\circ

) is correct because the angle of incidence at which the reflected light is completely polarized is Brewster's angle, given by

\mu = \tan \theta_P

, where

\mu

is the refractive index.
