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

$A$ ray of light is incident at a polarising angle such that its deviation is $24^{\circ}$. Then the angle of incidence is: (in $^{\circ}$)

$A$ 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

If the polarising angle for an air-glass interface is $56.3^o$,what is the angle of refraction in glass (in $^o$)?

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

The angle of polarisation for any medium is $60^{\circ}$. What will be the critical angle for this medium?
