Spring Wave, Plastic
The plastic spring for testing waves is used to observe phase reversal at the fixed end of wave pulses and to test fundamental and multiple vibrations. Use it in your experiments to determine the speed of propagation of transverse and longitudinal waves. This lightweight and non-tangling plastic spring is an excellent hands-on demonstration.
