Which element is responsible for sound transmission?

The choice of air particles as the element responsible for sound transmission is correct because sound is a mechanical wave that requires a medium to travel through. In the case of sound, air acts as the medium through which sound waves propagate. When an object vibrates, it causes the air particles around it to also vibrate, creating a wave of pressure changes that travel through the air.

This ability of air particles to transmit sound relies on the principles of compressions and rarefactions; as particles collide and transfer energy, the sound waves move away from the source. While water molecules can also transmit sound, air is primarily recognized as the medium in everyday sound transmission. Electricity does not transmit sound directly; it can, however, generate sound when used in speakers and other devices. Silence, on the other hand, represents the absence of sound and does not facilitate its transmission.
