Air Track - Longitudinal Waves
Purpose
To demonstrate longitudinal waves with a series of spring-coupled air track gliders.
Equipment
Large air track, several small gliders connected by light springs.
Setup Time
5 min.

Description
Several identical gliders are connected by springs, with the two end gliders fixed or attached by springs to the ends of the air track. Longitudinal waves can be created which reflect off the (fixed) ends, and standing waves can be created in the system.
