Question

what is longitudinal wave made off?​

Answer 1

Answer:

Longitudinal waves include sound waves (vibrations in pressure, a particle of displacement, and particle velocity propagated in an elastic medium) and seismic P-waves (created by earthquakes and explosions). In longitudinal waves, the displacement of the medium is parallel to the propagation of the wave.
