Question

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

Answer 1

The correct option is B Reflected light is polarised with its electric vector perpendicular to the plane of incidence
