During the propagation of a longitudinal wave, in the region of compressions and rarefactions
During the propagation of a longitudinal wave, in the region of compressions and rarefactions
density varies
density remains constant
there is heat transfer
Boyle's law is obeyed
Solution
When a longitudinal wave propagates through solid liquid or gas then the particles of medium start oscillating about there mean position up and down in the same direction in which the wave travels. At any instant there are point in space where density is height called compression and the point where density is lowest called rare faction.
