MHT CET 2025 Physics question

The phenomenon, which is not due to total internal reflection is

(A)mirage on hot summer days
(B)brilliance of diamond
(C)difference between apparent and real depth of a pondCorrect
(D)working of optical fibre

Answer: (C)

Solution

Total internal reflection (TIR) occurs when light travelling from a denser to a rarer medium meets the interface at an angle greater than the critical angle. A mirage is produced by TIR of light from successive hot, rarer air layers near the ground, so (A) is due to TIR. The brilliance of diamond comes from its small
