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

$A$ 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:

The critical angle of a certain medium is $\sin^{-1}\left(\frac{3}{5}\right)$. The polarizing angle of the medium is

The Brewster's angle $i_b$ for an interface should be

$A$ beam of light both reflects and refracts at the surface between air and glass. The refractive index of the glass is $1.4$. If the refracted and the reflected rays are perpendicular to each other,then the angle of incidence in the air is

Light,whose electric field vectors are completely removed in the plane of incidence by using a good Polaroid,is incident on the surface of a prism at Brewster's angle. Choose the most suitable option for the phenomenon related to the prism.
