Essential properties of the medium for wave propagation:
(i) Elasticity: So that particle can return to their mean position, after having been disturbed.
(ii) Inertia : So that molecules can save energy and overshoot their mean position.
(iii)Minimum friction amongst the particles of the medium.
(iv)Uniform density of the medium.
Mechanical stressing: When a material undergoes a mechanical treatment, its resistivity changes due to mechanical distortion of the crystal structures. The localized strain produc
