When unpolarised light from air is incident on the surface of a medium of refractive index $\sqrt{3}$, the reflected light is totally polarised. The angle of refraction is (in $^{\circ}$)

What is the Brewster angle for air to glass transition (in $^{\circ}$)? (Refractive index of glass $= 1.5.)$

$A$ 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.......$^o$

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

$A$ ray of light is incident from a denser to a rarer medium. The critical angle for total internal reflection is $\theta_{iC}$ and Brewster's angle of incidence is $\theta_{iB}$,such that $\sin \theta_{iC} / \sin \theta_{iB} = \eta = 1.28$. The relative refractive index of the two media is

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