Question

Wat is the importance air in transmission of sound ?

Answer 1

Sound waves are created by a disturbance that then propagates through a medium (e.g., crust, water, air). Individual particles are not transmitted with the wave, but the propagation of the wave causes particles (e.g., individual air molecules) to oscillate about an equilibrium position.

Answer 2

because sound propagate when particles are in vibration if there is no air then no sound propagate
