The changes in pressure an volume of air, when sound wave passes through air are

(A): The longitudinal waves are called pressure waves. (R): Propagation of longitudinal waves through a medium involves changes in pressure and volume of medium, when compression and rarefaction are formed.

When a sound wave travels through air, the air particles

During propagation of sound wave through air medium

Sound waves in air are ________ .

Assertion : Sound waves travel in the form of compressions and rarefactions in air. Reason : Because crests and troughs cannot be sustained in air, therefore, sound waves cannot travel through air in the form of transverse waves.
