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

A ray of unpolarised light is incident on a glass plate at the polarizing angle if incident 57^@ . Now,

A ray of unpolarised light is incident on a glass plate of refractive index 1.54 at polarising angle, then angle of refraction is :

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 in air is incident on a glass plate at polarising angle of incidence. It suffers a deviations of 22^(@) on entering glass. The angle of polarisation is
