The refractive index of a medium is $\sqrt{3}$. If unpolarised light is incident on it at the polarizing angle of the medium,then the angle of refraction is......$^o$

Light,whose electric field vectors are completely removed in the plane of incidence by using a good Polaroid,is incident on the surface of a prism at Brewster's angle. Choose the most suitable option for the phenomenon related to the prism.

Consider a tank made of glass (refractive index $1.5$) with a thick bottom. It is filled with a liquid of refractive index $\mu$. $A$ student finds that,irrespective of what the incident angle $i$ (see figure) is for a beam of light entering the liquid,the light reflected from the liquid-glass interface is never completely polarized. For this to happen,the minimum value of $\mu$ is

$A$ ray of light strikes a glass plate at an angle of $60^{\circ}$. If the reflected and refracted rays are perpendicular to each other,the refractive index of glass is

For a given medium, the polarizing angle is $60^o$. What will be the critical angle for this medium?

$A$ ray of unpolarised light is incident on a glass surface of refractive index $1.73$ at the polarizing angle. The angle of refraction will be. [Take $\tan 60^{\circ} = 1.73$] (in $^{\circ}$)
