Longitudinal Waves Vs Transverse

Longitudinal waves are a type of mechanical wave where the particle displacement is parallel to the direction of wave propagation. In these waves, particles of the medium oscillate back and forth along the same direction that the wave travels, creating regions of compression and rarefaction. Sound waves in air are a common example of longitudinal waves, where the vibrations of air molecules transmit sound energy through the medium.

Transverse waves, in contrast, are mechanical waves where the particle displacement is perpendicular to the direction of wave propagation. In these waves, particles move up and down or side to side, while the wave itself travels horizontally. A classic example of transverse waves is found in waves on a string, such as those produced when a guitar string is plucked, where the displacement of the string occurs perpendicular to the direction of the wave's travel.
