Question
Sound waves are ________ in nature.
- Longitudinal only
- Transverse only
- Longitudinal and mechanical
- Transverse and mechanical
Hint:
Sound waves are longitudinal and mechanical
The correct answer is: Longitudinal and mechanical
- Sound waves are longitudinal waves.
- Because the particles of the medium move back and forth parallel to the direction of wave propagation.
- Sound waves are mechanical waves.
- Because they need a material medium for propagation.
- So, the correct option is c.
