A generator for producing mechanical vibrations when used with function generator. The input is fed to coil which is mounted within the field of cylindrical permanent magnet. The unit is fuse protected. Locking mechanism protects from shock during transit and when changing accessories. Max input 6V/1A. Dimensions (L x W x H): 100 x 100 x 120 mm.

For use with SI30825 for demonstrating the relationship between frequency and the number of vibrational nodes. Dimensions (Dia.): 290mm.

For use with SI30825. A thin layer of sand is spread over the plate and resonance patterns (""Chladni"" figures) can be observed at certain frequencies. The plate resonances are audible.

Steel strips giving six vibrating lengths. For use with SI30825. Fundamental frequencies at 11, 15, 21, 36 and 50 Hz can be readily observed. Interesting standing waves can be seen up to 300 Hz and heard up to 900 Hz.

For use with SI30825. For demonstrating standing waves. Dimensions (L): 2 metres.

This quality spring is ideal for producing longitudinal waves with vibration generator connected to a signal generator. Spring constant 4.7 N/m. Closed Dimensions (L x Dia.): 155 x 27 mm.

This vibration generator is a sturdy, user-friendly tool for providing electronically controlled waves. Ripples can be created for the study of wave motion. (Recommended for use with square wave generator). Dimensions: 140 mm, overall diameter: 114 mm. The amplitude is +/- 3 mm.

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.

To demonstrate form and propagation of longitudinal and transverse waves. This simple wave demonstrator rotates a set of cams that raise and lower 24 vertical rods with plastic highlighted tips for easy viewing. It is 480 mm long, strong, and almost silent in operation. Lubrication is not required and students can see from both sides. Eight of the rods are turned at 90 degrees to simulate transverse wave motion. The handle is fitted with a circular scale marked in degrees of rotation.
