Question

Why does a coin at the bottom of a tumbler filled with water appear to be raised?

  1. Reflection of light
  2. Transmission of light
  3. Refraction of light
  4. Absorption of light

hintHint:

Refraction

The correct answer is: Refraction of light


    • This is because of refraction of light.
    • As light passes from water to air, it bends away from the normal.
    • The refracted rays appear to come from a point above the actual position of the coin, hence the coin appears raised.
    • So, the correct option is c.
