The Polarising Angle Of Glass Is 57 A Ray Of Physics Question

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
