MCQ
A cut diamond sparkles because of its
- AHardness
- ✓High refractive index
- CEmission of light by the diamond
- DAbsorption of light by the diamond
✓
Answer
Correct option: B.
High refractive index
b
(b) Due to high refractive index its critical angle is very small so that most of the light incident on the diamond is total internally reflected repeatedly and diamond sparkles.
