Overhead Projector Ripple Tank

Now you can create real moving waves that the whole class can observe!

Our Overhead Projector Ripple Tank allows you to demonstrate wave propagation, reflection, refraction, diffraction and interference on a large scale. Just place the tank on the stage of your projector. Add water to the tank and position any of the reflectors or barriers. Use the manual wave generator to send visible waves toward the reflector and observe the results. See how straight and curved reflectors work. Observe how waves behave as they enter a new medium (shallow water). Test the effect of wavelength on diffraction patterns. Student groups can also experiment individually without using projectors! Set includes 11"x14" tank, reflectors and barriers, manual wave generator, and teacher's guide. Save when you buy 6 or more!
