Critical angle for a certain medium is $\sin ^{-1}(0.6)$. The polarizing angle of that medium is

$A$ transparent medium shows a relationship between $\sin i$ and $\sin r$ as shown in the graph. If the speed of light in vacuum is $c$,the Brewster angle for the medium is: (in $^{\circ}$)

$A$ 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:

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

Choose the $CORRECT$ statement from the following. Brewster's angle for a transparent medium is

$A$ ray of light is incident on a transparent glass slab of refractive index $1.62$. The reflected and the refracted rays are mutually perpendicular. The angle of incidence is.......$^o$
