Question

Sonic boom is a phenomenon caused by the sound emitting objects moving at _____.

  1. A supersonic speed
  2. A speed equal to the speed of sound in that medium
  3. A speed less than the speed of sound
  4. Any speed

hintHint:

The sonic boom is the phenomenon caused by a sound-emitting object when it moves at a supersonic speed.

The correct answer is: A supersonic speed


    • A sonic boom is caused when a sound-emitting object moves faster than the sound travels in a medium.
    • The speed supersonic wave is greater than the speed of the sound.
