The polarising angle of glass is 57⁰. A ray of light which is incident at this angle will have an angle of refraction as
Options
(a) 43⁰
(b) 25⁰
(c) 38⁰
(d) 33⁰
Correct Answer:
33⁰
Explanation:
Given, θₚ = 57⁰
According to Brewster’s law, we have
θₚ + r = 90⁰ ⇒ r = 90⁰ – θₚ ⇒ r = 90⁰ – 57
Angle of refraction, r = 33⁰
