Standing Transverse Waves (Driven Waves in Rubber Tubing) (3B22.10)

Description:

A long piece of rubber tubing is stretched out horizontally and run over a pulley at one end, then tensioned with a hanging weight. At the other end a revolving bar strikes the tubing at a frequency which can be adjusted with a motor speed controller. Transverse waves of various frequency can thus be sent along the tubing, and when the right frequencies are reached the tubing vibrates in various standing wave modes. 1 kg and 0.25 kg masses can be used to vary the tension.
