401501NA Wave Trough With Stroboscope
Overview
Using water waves to demonstrate wave propagation, reflection, refraction, interference, diffraction, and the Doppler effect.
The oscillations of a diaphragm in the frequency generator are transmitted, in the form of fluctuations in air pressure, via variously-formed wave-generators to the surface of the water. Single wave generation, namely generation of a wave packet through key head. Transillumination of the trough projects an image of the waveforms onto a vertical screen via a plane mirror (possibility of placing the trough on overhead projector). An image of a standing wave is produced by synchronising a stroboscopic light with the wave propagation.
