Expert Answer:

  • Sound propagates in a medium as a series of compressions and rarefaction.
  • A longitudinal wave is a wave when the individual particles vibrate parallel to the direction of propagation of wave.
  • Sound waves also propagate in the same manner, and hence they are longitudinal waves.



  • A longitudinal wave is composed of alternate compressions and rarefactions.
