Application +4 | -1

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 at the Brewster angle, the reflected light is completely polarized, and the tangent of this angle equals the refractive index.
