Question

A cut piece of diamond appears to sparkle much more than an identically cut piece of glass. Why?

• A. Because Diamond, unlike glass, has smaller critical angle and hence is a poor reflector of Light
• B. Because Diamond, unlike glass, has smaller critical angle and hence is a better reflector of Light
• C. Because Diamond, unlike glass, has larger critical angle and hence is a better reflector of Light
• D. Because Diamond, unlike glass, has smaller critical angle and hence is a poor reflector of Light
• E. Because although Diamond and glass, has same critical angle, Diamond has a higher Refractive Index.

Answer 1

The correct option is B

Because Diamond, unlike glass, has smaller critical angle and hence is a better reflector of Light
