<!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> What is the importance of air in transmission of sound?

Answer 1

<!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> Air acts as a medium for the transmission of sound. Sound is essentially produced by the vibration of air particles propagating in a direction. Sound cannot travel without a medium, and thus, we cannot listen to sounds in space because of the absence of air.
