Q. The polarising angle for a medium is $60^°$. The critical angle for the medium is

In This post you will get answer of Q.
The polarising angle for a medium is $60^°$. The critical angle for the medium is

Solution:

Here, $i_p = 60^°$

Refractive index of the medium,

$mu=tani_{p}=tan60^{°}=sqrt{3}$

Now, critical angle of the medium, $i_{c}$

$=sin^{-1}left(frac{1}{mu}right)=sin^{-1}left(frac{1}{sqrt{3}}right)$
