Question

how the sound moves in air?

Answer 1

heya!


here is your answer

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.
