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......$^o$

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

Light is incident at an angle $i$ on a glass slab. The reflected ray is completely polarised. The angle of refraction is

The angle of incidence at which reflected light is totally polarized for reflection from air to glass (refractive index $n$) is:

When the angle of incidence on a material is $60^\circ,$ the reflected light is completely polarized. The velocity of the refracted ray inside the material is (in $m/s$)

$A$ camera equipped with a polariser is placed on a mountain to record only the reflected image of the sun from the surface of a sea,as shown in the figure. If the sun rises at $6.00 \, AM$ and sets at $6.00 \, PM$ during the summer,then at what time in the afternoon will the recorded image have the lowest intensity? Assume there are no clouds and the intensity of the sun at the sea surface is constant throughout the day. (Refractive index of water $= 1.33$)
