Question

If any explosion takes place at the bottom of a lake, what type of shock waves in water will take place?

Answer 1

1. An explosion in a lake produces shock waves.
2. Shock waves produce a massive increase in water pressure.
3. The pressure thus created creates compression and rarefaction of water.
4. This is a characteristic behaviour of longitudinal waves.

Therefore, shock waves created by explosions at the bottom of a lake are longitudinal waves.
