Unpolarised light is incident from air on plane surface of a material of refractive index μ . At a particular angle of incident 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?
Options
- Ai = sin - 1 1 μ
- BReflected light is polarized with its electric vector perpendicular to the plane of incidence
- CReflected light is polarized with its electric vector parallel to the plane of incident
- Di = tan - 1 1 μ
Correct answer
B. Reflected light is polarized with its electric vector perpendicular to the plane of incidence
Step-by-step solution
when reflected light rays and reflected rays are perpendicular, reflected light is polarised with electric field vector perpendicular to the plane of incidence. Also. Brewster's law μ = tan i .
