Question
When a sound producing object moves at a speed greater than that of sound in a medium, it produces _____.
- Sound waves
- Thunder
- Shock waves
- Light waves
Hint:
When a sound-producing object moves at a speed greater than that of sound in a medium, it produces shock waves.
The correct answer is: Shock waves
- A shock wave moves faster than the speed of sound.
- It creates strong pressure in any kind of medium like solid or liquid.
- If an object moves at a greater speed than the sound wave, it produces shock waves.
