Physics Question on Refraction of Light
The critical angle for total internal reflection in diamond is 24.5∘ . The refractive index of the diamond is
A
2.45
B
1.41
C
2.59
D
1.59
Answer
2.45
Explanation
Solution
Given, critical angle C=24.5∘
For total internal reflection
μ=sinC1=sin24.5∘1μ
=2.45[sin24.5∘=0.414]
