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 refractive index of a material is equal to the tangent of the polarising angle. This is called:

The angle of incidence at which reflected light is completely polarized for reflection from air to a medium of refractive index $n$ is:

Unpolarised light is incident from air on a plane surface of a material of refractive index $\mu$. At a particular angle of incidence $i$,it is found that the reflected and refracted rays are perpendicular to each other. Which of the following options is correct for this situation?

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

Unpolarized light of intensity $I_0$ is incident on the surface of a block of glass at Brewster's angle. In that case,which one of the following statements is true?
