Question

how does sound travel in air??

Answer 1

Sound (in air) is made when air molecules vibrate and move (away from the vibrating source) in a pattern called waves, or sound waves. Sound is a mechanical, longitudinal wave (that moves in all directions) and travels in waves of compressions and rarefactions (expansion) as it successively passes through a medium.

Answer 2

Sound travels through the air in the form of vibrations. These vibrations cause particles of air to compress together and this causes the air around them to move in such a way that they are driven in waves away from the source
