Question
The sound propagates in a gaseous medium by:
✓

Answer

  1. Longitudinal waves
Explanation:
For transverse wave, cohesion is an important property in the medium through which the wave energy can be transported. Gas does not have such a cohesion property. Hence there is no chance for transverse waves to be propagated through gas medium. So the sound propagates in a gaseous medium by longitudinal wave.
