Unpolarised light is incident from air on a plane surface of a material of refractive index ''. 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?

A

i=sin⁡−1(1μ)i = \sin^{-1}\left(\frac{1}{\mu}\right)

B

Reflected light is polarised with its electric vector perpendicular to the plane of incidence

C

Reflected light is polarised with its electric vector parallel to the plane of incidence

D

i=tan⁡−1(1μ)i = \tan^{-1}\left(\frac{1}{\mu}\right)

Step-by-Step Solution

When reflected light rays and refracted rays are perpendicular, reflected light is polarised with electric field vector perpendicular to the plane of incidence
