$A$ ray of light is incident on the surface of a glass plate at Brewster's angle $\phi$. If $\mu$ is the refractive index of glass with respect to air,then the angle between the reflected and the refracted ray is:

For a given medium,the polarizing angle is $60^{\circ}$. The critical angle for this medium is . . . . . .

An unpolarised light beam strikes a glass surface at Brewster's angle. Then

Light is incident on a glass surface at a polarizing angle of $57.5^{\circ}$. Then the angle between the incident ray and the refracted ray is: (in $^{\circ}$)

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 $^{\circ}$)

Can reflection result in plane polarised light if the light is incident on the interface from the side with higher refractive index?
