Q. The critical angle of a certain medium is $\sin^{- 1}{\left( \frac{3}{5} \right).}$ The polarizing angle of the medium is
A) $\tan^{- 1}\left( \frac{4}{3} \right)$
B) $\tan^{- 1}\left( \frac{3}{4} \right)$
C) $\tan^{- 1}\left( \frac{5}{3} \right)$
D) $\sin^{- 1}\left( \frac{4}{5} \right)$
Explanation
(c) $\tan i = \frac{1}{\sin C}$
$\cot i = \sin\left\lbrack \sin^{- 1}\left( \frac{3}{5} \right) \right\rbrack$
$\tan{i = \frac{5}{3}}$
$\ \ \ \ \ \ \ i = \tan^{- 1}\left( \frac{5}{3} \right)$
