A ray of light is incident on the surface of a glass plate of refractive index \(\sqrt{3}\) at the polarising angle. The angle of refraction of the ray is
- A \(30^{\circ}\)
- B \(45^{\circ}\)
- C \(60^{\circ}\)
- D \(37^{\circ}\)
Answer & Solution
Correct Answer
(A) \(30^{\circ}\)
Step-by-step Solution
Detailed explanation
Given, refractive index of glass plate, \(\mu=\sqrt{3}\) Polarising angle \(\theta\) of incident light is given as, \(\mu=\tan \theta\) or \(\sqrt{3}=\tan \theta \text { or } \theta=\tan ^{-1}(\sqrt{3})\) \(\therefore\) angle of incident, \(\theta=60^{\circ}\)…
