We know that sound travel through waves. But what is the reason behind the traveling of a sound in wave. Is the sound travel in another way?

Expert Answer:

Sound waves are characterised by motion of particles in a medium and are called mechanical waves. Sound propagates in a medium as a series of compressions and rarefactions. It travels in the form of a longitudinal wave where the individual particles vibrate parallel to the direction of propagation of the waves.
Hence, they are known as longitudinal waves. It is composed of alternate compressions and rarefactions.
This is only way a sound wave can travel.
