Which of the following is not due to total internal reflection?

A

Difference between apparent and real depth of a pond

B

Mirage on hot summer days

C

Brilliance of diamond

D

Working of optical fibre

Step-by-Step Solution

  1. The difference between the apparent and real depth of a pond is due to the simple refraction of light at the plane interface between water (denser medium) and air (rarer medium), not total internal reflection.
  2. Mirage on hot summer days, the brilliance of diamonds, and the propagation of light through optical fibres are all phenomena based on the principle of total internal reflection (TIR).
