Polarisation question from JEE Main 2004 (AIEEE)

Q63JEE Main 2004 · AIEEEEasy

Polarisation

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

Show answer and solution

Answer: (d)

Brewster's law: $\tan i_p = n$ for light going from air to a medium of index $n$ .
$i_p = \tan^{-1}(n)$
So the answer is (d).
