Vedclass · Answer

(A) When a longitudinal wave propagates through a medium (solid,liquid,or gas),the particles of the medium oscillate about their mean positions in the same direction as the wave propagation.At any given instant,there are regions where the particles are crowded together,resulting in high density,known as compressions.Conversely,there are regions where the particles are spread apart,resulting in low density,known as rarefactions.Therefore,the density of the medium varies periodically during the propagation of a longitudinal wave.

During the propagation of a longitudinal wave,in the region of compressions and rarefactions,
