- Explain the concept of sonic boom.
- Differentiate sound waves and light waves.
- When an object travels with speed greater than that of sound, the speed is called a supersonic speed. Aircraft at supersonic speed produces shock waves and the pressure variation in such shock wave leads to a sharp and loud sound, called sonic boom
- Differences between sound waves and light waves are
|They are longitudinal in nature.
||They are transverse in nature.
|Speed is low, i.e. 330 m/s.
||Speed is very high, i.e. 3x108 m/s.
