$A$ 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

When an unpolarized light falls at a particular angle on a glass plate (placed in air), it is observed that the reflected beam is linearly polarized. The angle of the refracted beam with respect to the normal is . . . . . . . $(\tan ^{-1}(1.52)=57.7^{\circ}$, refractive indices of air and glass are $1.00$ and $1.52$, respectively) (in $^{\circ}$)

When unpolarised light from air is incident on the surface of a medium of refractive index $\sqrt{3}$, the reflected light is totally polarised. The angle of refraction is (in $^{\circ}$)

When unpolarized light is incident from air onto glass $(\mu = 1.5)$,then:

Let the speed of light in a medium be $V$ and the polarising angle be $i_p$. If $C$ is the speed of light in vacuum,what is the relation between them?

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......$^o$
