Q. Brewster’s angle in terms of refractive index ($n$) of the medium
A) $\tan^{- 1}{\lbrack\sqrt{n}\rbrack}\ $
B) $\sin^{- 1}\lbrack n\rbrack$
C) $\sin^{- 1}\left\lbrack \sqrt{n} \right\rbrack$
D) $\tan^{- 1}\lbrack n\rbrack$
Explanation
(d) Refractive index of a medium
$n = \tan i_{p}$
Where $i_{p} =$ Brewster’s angle
$\Rightarrow i_{p} = \tan^{- 1}\lbrack n\rbrack$
