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 the above
Hint:
Sound waves are mechanical waves that are considered a disturbance that travels through a medium.
The correct answer is: The sound wave is a disturbance that is transported through a medium
- Sound waves are a strong form of energy.
- They travel as vibration and require a strong medium to transmit.
- They are the mechanical waves that are transmitted through a medium.
