Question

why does sound produce waves while travelling?

Answer 1

Traveling sound waves. Vibrating objects can produce sound. The vibrating object can be a string, an air column, a membrane, etc. When the object moves outward, it pushes the air molecules, creating a region of high pressure.

Answer 2

Sound waves traveling through air are indeed longitudinal waves with compressions and rarefactions. As sound passes through air (or any fluid medium), the particles of air do not vibrate in a transverse manner. Do not be misled - sound waves traveling through air are longitudinal waves.
