Question

Why are sound waves considered mechanical waves?

  1. The sound wave is a disturbance that is transported through a medium.
  2. The particles of sound waves vibrate in a direction perpendicular to the wave’s propagation direction.
  3. The particles of sound waves always tend to come back to their original positions when set in a wave motion.
  4. All the above

hintHint:

The sound wave is a disturbance that is transported through a medium

The correct answer is: The sound wave is a disturbance that is transported through a medium.


    sound wave are considered mechanical waves because they require a medium to propagate.
