TYPES OF WAVES
Mechanical waves are waves created by the
disturbance of a material substance or medium
as a result of repeated periodic motion of the
particles of the medium. The energy is
propagated as a result of the motion of the
particles of the medium, but medium remains at
its previous position.
Mechanical waves are classified as:
1.Longitudinal waves

are moving away from a common point where
pressure and density are at a minimum.
