Question

Sonic boom is a sudden

• A. Loud noise by passing train
• B. Sound of overflying helicopter
• C. Vibrations by overflying supersonic jet
• D. Continuous sound by industrial and commercial areas

Answer 1

Answer: (C)

Vibrations by overflying supersonic jet

A sonic boom is the sound of the shock wave created when an object travels through air faster than the speed of sound. It generated an enormous amount of sound energy. The aircraft flying faster than the speed of sound, it produces a sonic boom when it flies past. All the sound waves are combined together and create a boom because at that speed they cannot propagate ahead of the plane. It is a continuous effect while the object continues to fly at supersonic speed and is heard and observed by people present at that point where such intersection of sound waves occur. It is a very loud noise which can cause damage to hearing and contribute to noise pollution.

Hence, the correct answer is 'Vibrations by overflying supersonic jets'.
