What is the value of refractive index of a medium of polarizing angle 60°?

Polarizing angle, ${\mathrm{i}}_{\mathrm{p}}$ = 60^o 

Therefore, refractive index of the medium is, 

                    $\boxed{\mathrm{\mu } = \tan {\mathrm{i}}_{\mathrm{p}}}$ 

$\Rightarrow$                $\mathrm{\mu } = \tan 60°$ 

$\Rightarrow$                $\mathrm{\mu } = \sqrt{3}.$
