The apparatus is used for demonstrating longitudinal and transverse waves. It is supplied with a drive shaft with a crank which acts on a number of vertical rods as it rotates. Each rod has a white marking at the top. Eight of the rods are supplied with an angular extension which makes it possible to observe the corresponding longitudinal wave. A 360 degree scale is mounted at the crank to enable the phase angle to be determined.
