Detailed explanation-1: -Sound wave through air is a longitudinal wave. Light wave, radio wave and X-ray are examples of transverse waves .
Detailed explanation-2: -What are the familiar examples of longitudinal waves? Tsunami waves, seismic-P waves, sound waves, and vibration in spring are some of the familiar examples of longitudinal waves.
Detailed explanation-3: -Sound waves are longitudinal waves, meaning that the waves propagate by compression and rarefaction of their medium. They are termed longitudinal waves because the particles in the medium through which the wave travels (air molecules in our case) oscillate parallel to the direction of motion.
Detailed explanation-4: -Plucking a guitar string is an example of transverse wave of string vibration, while sound produced by it gives you a longitudinal wave in the air.
