Question

The refractive index of the medium, for the polarising angle ${60}^o$ is?

• A. $1.732$
• B. $1.414$
• C. $1.5$
• D. $1.468$

Answer 1

The correct option is A $1.732$

Relation between refractive index of medium and polarising angle is given by
$n=\tan i_p$
Given : Polarising angle $i_p={60}^o$
So, refractive inedx $n=\tan \left({60}^o\right)=1.732$
