The video shows a hand making longitudinal and transverse waves1 on a slinky. The audio describes longitudinal and transverse wave2 characteristics.
Transcript
In a longitudinal wave3, the disturbance that makes up the wave is along the direction in which the wave travels. Longitudinal waves are also referred to as compression waves. In a transverse wave, the disturbance that makes up the wave is perpendicular4 to the direction in which the wave travels.
