When unpolarised light is incident on a plane glass plate at Brewster’s angle, then which of the following statements is correct?

When unpolarized light is incident on a plane glass plate at Brewster’s angle, then which of the following statements is correct?

A ray of unpolarised light is incident on a glass plate at the polarising angle theta_p . Then

A : When an unpolarised light is incident on a glass plate at Brewster angle, the reflected ray and refracted ray are matually perpendicular. R : The refractive index of glass is equal to sine of the angle of polarisation.

Assertion (A) : When an unpolarised light is incident on a glass plate at Brewster angle, the reflected ray and refracted ray mutually perpendicular Reason (R ) : The refractive index of glass is equal to sine of the angle of polarisation.

A ray of light incident on a medium at polarising angle.what will be the angle between the reflected and the refracted rays? Or, an unpolarised ray of light is incident on a rectangular glass block at Brewster's angle. What will be the angle between the reflected and the refracted rays?
