उत्तर
The following are the three characteristics of the medium required for the propagation of sound:
(i) The medium must possess elasticity so that the particles of the medium have the tendency to return back to their original positions.
(ii) The medium must be frictionless so that there is no loss of energy during transmission.
(iii) The medium must possess inertia such that the particles of the medium have the ability to store energy.
