हिन्दीUnpolarised 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?
Correct answer · Option 2
Reflected light is polarised with its electric vector perpendicular to the plane of incidence
Explanation
According to Brewster's law, when reflected and refracted rays are perpendicular, \( \tan i = \mu \), which implies \( i = \tan^{-1}(\mu) \). Also, the reflected light is completely polarized with its electric field vector perpendicular to the plane of incidence.
