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 $^{\circ}$)?

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

When a light ray is incident on the surface of a medium,the reflected ray is completely polarized. Then the angle between the reflected and refracted rays is (in $^{\circ}$)

$A$ ray of light is incident on the surface of a glass plate at Brewster's angle $\phi$. If $\mu$ is the refractive index of glass with respect to air,then the angle between the reflected and the refracted ray is:

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