What is a Longitudinal wave?
Longitudinal waves are waves that transfer energy in the same direction as the
disturbance in the medium of propagation. Like transverse waves, longitudinal
waves may consist of single or multiple pulses. All longitudinal waves consist of
regions of high and low density known as condensations and rarefactions that
oscillate around local positions of equilibrium parallel to the path of energy
transfer. Sound waves are longitudinal waves. Sound waves propagating through
air consist of a series of pressure fluctuations above and below atmospheric
pressure.
