$A$ ray of light is incident at the polarising angle $\theta$ on an air-glass interface. If $\lambda_{a}$ and $\lambda_{g}$ are the wavelengths of light in air and glass respectively,then:

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 $^{\circ}$)?

The angle of polarisation for a medium is $60^o$. What will be the critical angle for this medium?

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

$A$ beam of light strikes a piece of glass at an angle of incidence of $60^{\circ}$ and the reflected beam is completely plane-polarized. 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 $^{\circ}$)
