Mechanical Waves

The existence of medium is essential for propagation. The Method of energy propagation in which disturbance propagates with definite velocity without changing its form is called Mechanical Wave.
Energy and momentum propagates by motion of particles of medium. But medium remains at previous position.
The mass transfer does not take possible here. The Propagation is possible due to property of medium like elasticity and inertia.
Examples: vibration of string, vibration of string, the surface wave produced on the surface of solid and liquid, sound waves, tsunami waves, earthquake P-waves, ultra sounds, vibrations in gas, and oscillations in spring, internal water waves, and waves in slink etc.
Mechanical waves are of two types:
  1. Transverse Wave
  2. Longitudinal Wave.
