At what angle of incidence $i$ will the light reflected from water be completely plane-polarized (in $^\circ$)? (Given refractive index of water $\mu = 1.33$)

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

When a light ray is incident on the surface of a medium,the reflected ray is completely polarized. Then the angle between the reflected and refracted rays is (in $^{\circ}$)

Explain the polarisation of light by reflection,state Brewster's law,and derive its formula.

An unpolarized light is incident from air on the boundary of a denser medium having refractive index $\mu$ at polarizing angle $i_p$. Which of the following is correct?

$A$ parallel beam of monochromatic unpolarised light is incident on a transparent dielectric plate of refractive index $\mu = \sqrt{3}$. The reflected beam is completely polarised. Then the angle of incidence is....$^o$
