This apparatus uses modern technology to completely update the Ripple Tank concept to provide a compact and elegant method of showing the wave phenomena of diffraction, refraction, reflection and interference with none of the usual problems. The white light source can be switched between constant illumination and strobe to give either moving or frozen images on the screen. In the strobe mode the light source is synchronized to the wave generator so that perfectly static patterns are displayed. The wave frequency can be varied giving wavelengths in the tank ranging from several cm to a few mm.
