WAVE MOTION APPARATUS [Wavemotion]

Demonstrates both longitudinal and transverse wave motion. Comprises a number of eccentric discs supporting a series of metal rods. By rotating a handle at one end of the shaft holding the discs transverse types are generated, and longitudinal types are obtained by a series of bent rods at one end of the apparatus.
