At what angle of incidence,the light reflected from a glass slab will become completely polarised,if the angle of refraction at that incident angle is $33.6^{\circ}$ (in $^{\circ}$)?

$A$ 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 $= 1.33$)

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 unpolarised light beam strikes a glass surface at Brewster's angle. Then

An unpolarized light is incident from air on the boundary of a denser medium having refractive index $\mu$ at polarizing angle $i_p$. Which of the following is correct?

The angle of polarisation for any medium is $60^{\circ}$. What will be the critical angle for this medium?
