List any two differences between transverse and longitudinal waves. What is the nature of sound waves in air.
(i) In transverse waves, the particles of the medium vibrate in a direction perpendicular to the direction of propagation of the wave.
In longitudinal waves, the particles of the medium vibrate along the direction of propagation of the wave.
(ii) Transverse waves travel in the form of crests and troughs.
Longitudinal waves travel in the form of compressions and rarefactions.
Sound waves are longitudnal waves in nature.
