Question

For propagation of sound in a medium should posses :
1. Inertia
2. Elasticity
3. 1 and 2
4 rigidity

Answer 1

Answer:

For propagation of sound, medium must possess inertia and elasticity.

Elasticity is important so that the particles of the medium return back to their original place after being disturbed.

Inertia is important so that the particles of the medium store kinetic energy.

So, the correct option is (3).
