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.
A Slinky-type spring for wave demonstration, with a wooden storage stand. Stand helps protect the spring in storage and keep it in good condition. Closed Spring Dimensions (Dia. x L): 72 x 220 mm. Base Dimensions (L x W x H): 150 x 150 x 355 mm.
