Question

A ray of light is incident on the surface of a glass plate at an angle of incidence equal to Brewster's angle $\varphi$. If $\mu$ represents the refractive index of glass with respect to air, then the angle between reflected and refracted rays is .

• A. $90 + \varphi$
• B. $\sin^{- 1}(\mu\cos\varphi)$
• C. 90^o
• D. $90^{o} - \sin^{- 1}(\sin\varphi/\mu)$

Answer 1

Answer: (C)

90^o

Answer 2

At polarizing angle, the reflected and refracted rays are mutually perpendicular to each other.
