Assertion: When an unpolarised light is incident on a glass plate at Brewster angle, the reflected ray and refracted ray are mutually perpendicular.

Reason: The refractive index of glass is equal to tangent of the angle of polarisation.

View answer and explanation

Correct option: C

Assertion is true and Reason is false

Option C is correct because at Brewster's angle, the reflected and refracted rays are perpendicular, but the refractive index is equal to the tangent of the polarization angle, not the angle of polarization.
