Which is not an application of Total Internal Reflection:
- A Mirage
- B Brilliance of diamond
- C Advance sunrise and delayed sunset
- D Optical fibre
Answer & Solution
Correct Answer
(C) Advance sunrise and delayed sunset
Step-by-step Solution
Detailed explanation
While Mirage, Brilliance of diamond, and Optical fibre all rely on Total Internal Reflection (TIR), advance sunrise and delayed sunset are caused by atmospheric refraction. This happens because sunlight bends as it passes through layers of air with different densities before…
