Question
Why are sound waves considered mechanical waves?
- The sound wave is a disturbance that is transported through a medium.
- The particles of sound waves vibrate in a direction perpendicular to the wave’s propagation direction.
- The particles of sound waves always tend to come back to their original positions when set in a wave motion.
- All of the above
Hint:
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 waves require a medium to propagate hence, it is known as mechanical wave.
