AP EAMCET · PHYSICS · Ray Optics
A light ray is incident from a medium of refractive index 2 into a medium of refractive index \(\sqrt{3}\). The critical angle is
- A \(30^{\circ}\)
- B \(45^{\circ}\)
- C \(60^{\circ}\)
- D \(90^{\circ}\)
Answer & Solution
Correct Answer
(C) \(60^{\circ}\)
Step-by-step Solution
Detailed explanation
Given, absolute refractive index of medium-1 and 2 are given as \[ \mu_1=2 \text { and } \mu_2=\sqrt{3} \] \(\therefore\) Let \(i_c\) be the critical angle, then \(\sin i_c=\frac{1}{2 \mu_1}\)…
