When an unpolarised light beam is incident from air onto glass $(n = 1.5)$ at the polarising angle:

$A$ 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 $= 1.33$)

At what angle of incidence $i$ will the light reflected from water be completely plane-polarized (in $^\circ$)? (Given refractive index of water $\mu = 1.33$)

The polarizing angle of glass is $57^{\circ}$. $A$ ray of light which is incident at this angle will have an angle of refraction as (in $^{\circ}$)

An unpolarized light is incident on the plane interface of an air-dielectric medium as shown in the figure. If the incident angle is equal to the Brewster angle,identify the expression representing the reflected wave.

Unpolarized light of intensity $I_0$ is incident on the surface of a block of glass at Brewster's angle. In that case,which one of the following statements is true?
