WebTransverse and longitudinal waves are two types of mechanical waves, which involve the transfer of energy through a medium (e.g. water, air, a solid). Learn about transverse and longitudinal waves through the examples of a shaken rope and a sound wave. Finally learn about the difference between a single wave pulse and periodic waves. tbi vauxhall limited
