Explanation:
Detailed explanation-1: -Longitudinal waves are characterized by the motion of particles of the medium along the direction of wave propagation. Particles make to and fro motion in the direction of wave propagation and transfer energy to the neighbouring particles.
Detailed explanation-2: -When an object moves back and forth, it is called a vibration. Vibrations carry energy. Waves are a method of transporting energy.
Detailed explanation-3: -Longitudinal waves A longitudinal wave is one where all the particles of the medium (such as gas, liquid or solid) vibrate in the same direction as the wave.
