Question

Write the requisites of the medium for the sound wave to propagation.

Answer 1

Sound wave propagation requisites

Explanation:

For a medium to be able to propagate sound waves, it should have the following characteristics:  Elasticity, frictionless and have inertia.

1. Elastic for the particles to come back to their original position.
2. Should have inertia for the particles to be able to store mechanical energy.
3. Should be frictionless so that there is no loss of energy.

Sound travels through solids, liquids and gas. It does not travel through vacuum.

Answer 2

REQUISITES OF THE MEDIUM FOR THE SOUND WAVE TO PROPAGATE :

• The medium must be elastic so that its particles may come back to their initial positions after displacement on either side, i.e. the particles are capable of vibrating about their mean positions.
• The medium must have inertia so that its particles may store mechanical energy.
• The medium should be frictionless so that there is no loss of energy in propagation of sound through it.
