Waves > transverse and longitudinal

Introduce the concept of a transverse wave by drawing attention to a wave pulse as a displacement at right angles to the direction of travel along a rope.

Use this experiment when introducing transverse and longitudinal waves. Later it might also be used when introducing standing waves or factors that affect wave speed through a medium.

Another way of demonstrating the transverse motion of particles in a water wave.

Introduce transverse and longitudinal waves with a kinaesthetic experience. This can help students to understand and remember what each of these wave types are.

Lines of dynamics trolleys connected by springs make good models for both longitudinal and transverse waves. They are best used at advanced level, when investigating factors affecting wave speed.
