Question

Sound waves are ________ in nature.

  1. Longitudinal only
  2. Transverse only
  3. Longitudinal and mechanical
  4. 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.
