I want to learn sound as longitudinal wave

Expert Answer
Sound is form of energy. Sound is produced due to vibration of partciles present in the medium.
Sound requires medium for it propagation as it is a form of longitudinal waves.
Sound cannot travel through vacuum beacuse there are no particles present to vibrate. The vibration of particle is necessary condiction for the sound to be produced.
The particles in the air through which the sound travels travels parallel to the direction of sound waves. Thus, sound travels in the form longitudinal waves in air.
This back and forth motion of particle about its means position is known as vibration.
