Q. A ray of light is incident on the surface of a glass plate at an angle of incidence equal to Brewster’s angle $\phi$. If $\mu$ represents the refractive index of glass with respect to air, then the angle between reflected and refracted rays is
A) $90 + \phi$
B) $\sin^{- 1}{(\mu}\cos\phi)$
C) $90{^\circ}$
D) $90{^\circ} - \sin^{- 1}{(\sin^{- 1}{\phi/\mu}})$
Explanation
(c) At polarizing angle, the reflected and refracted rays are mutually perpendicular to each other
