Question
Why does a coin at the bottom of a tumbler filled with water appear to be raised?
- Reflection of light
- Transmission of light

Hint:
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.
