Wave Demonstrator Kit. This wave machine, which comes in kit form and must be self-assembled, is designed to demonstrate the theory of waves. The kit comprises: transverse wave machine with 80 arms spaced on nylon line with detachable weights to provide an example of transverse wave propagation in which movements of the rods create the waves; Two loaded elastic cords to illustrate transverse wave motion; An extension spring with weights, for the propagation of both longitudinal and transverse waves; teacher's book which describes the experiments and gives detailed quantitative analysis.
