Question

Unpolarised light is incident from air on a plane surface of a material of refractive index ‘μ’. 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. Reflected light is polarised with its electric vector parallel to the plane of incidence
• B. \(i=sin^{-1}\left(\frac{1}{\mu}\right)\)
• C. Reflected light is polarised with its electric vector perpendicular to the plane of incidence
• D. \(i=tan^{-1}\left(\frac{1}{\mu}\right)\)

Answer 1

The Correct Option is C

The correct option is (C): Reflected light is polarised with its electric vector perpendicular to the plane of incidence
