Mini Ripple Tank
Grades 6-12.
Modern technology has been used 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 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 that range from several centimeters to a few millimeters. Includes instructions.
