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

An unpolarized light beam travelling in air is incident on a medium of refractive index $1.73$ at Brewster's angle. Then

The angle of incidence at which reflected light is totally polarized for reflection from air to glass (refractive index $n$) is

At what angle of incidence,the light reflected from a glass slab will become completely polarised,if the angle of refraction at that incident angle is $33.6^{\circ}$ (in $^{\circ}$)?

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 $^{\circ}$)

An unpolarized light is incident on the plane interface of an air-dielectric medium as shown in the figure. If the incident angle is equal to the Brewster angle, identify the expression representing the reflected wave.
