When unpolarised light from air incidents on the surface of a medium of refractive index \(\sqrt{3}\), then the reflected light is totally polarised. The angle of refraction is
- A \(30^{\circ}\)
- B \(53^{\circ}\)
- C \(60^{\circ}\)
- D \(37^{\circ}\)
Answer & Solution
Correct Answer
(A) \(30^{\circ}\)
Step-by-step Solution
Detailed explanation
\( \tan \theta_p = n \) \( \tan \theta_p = \sqrt{3} \Rightarrow \theta_p = 60^{\circ} \) \( \theta_p + \theta_r = 90^{\circ} \) \( 60^{\circ} + \theta_r = 90^{\circ} \Rightarrow \theta_r = 30^{\circ} \)
