The brilliance of diamond is due to

A

shape

B

reflection

C

cutting

D

total internal reflection .

Text Solution

Verified by Experts

The correct Answer is:
D
Total internal reflection can occur only when a ray is incident on the surface of a medium whose refractive index is smaller than that of the medium in which the ray is travelling . Since the refractive index of air is 1.00029 and that of diamond is 2.42 , therefore brilliance of diamond is due to total internal reflection .
