Unpolarised light is incident from air on a plane surface of a material of refractive index At a particular angle of incidence it is found that the reflected and refracted rays are perpendicular to each other. Which of the following options is correct for this situation?
Reflected light is polarised with its electric vector perpendicular to the plane of incidence
Reflected light is polarised with its electric vector parallel to the plane of incidence
To solve this problem, we need to understand the condition given:The reflected and refracted rays are perpendicular to each other.This condition is satisfied at Brewster's angle, where the angle of incidence is such that:
