A sound wave is created by a series of compressions and rarefactions in the air, caused by the rapid back-and-forth movement of a vibrating object.
A sound wave is created in the air when a vibrating object causes surrounding air particles to oscillate, generating alternating compressions and rarefactions that propagate through the medium, transmitting the sound.
