Optics Question 552
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
[CPMT 1989]
Options:
A) $ 90+\varphi $
B) $ {{\sin }^{-1}}(\mu \cos \varphi ) $
C) 90o
D) $ 90^{o}-{{\sin }^{-1}}(\sin \varphi /\mu ) $
Show Answer
Answer:
Correct Answer: C
Solution:
At polarizing angle, the reflected and refracted rays are mutually perpendicular to each other.
