Wave Motion Apparatus.
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 waves are generated.
Longitudinal waves are obtained by a series of bent rods at one end of the apparatus.
