Longitudinal Standing Waves on a Spring
Demonstration of standing waves of longitudinal oscillations on a spring. A vibration generator powered by a sine wave generator is connected to one end of the spring – a longitudinal traveling wave is sent through the spring. After reflecting at the fixed end of the spring, the wave reflects back and the superposition creates a standing wave. By setting the appropriate excitation frequencies, we gradually excite the individual modes of standing waves.
