Mini Ripple Tank allows for detailed observation of all aspects of actual moving waves

Ripple tank wave generators are such a wonderful way to demonstrate the wave phenomena of reflection, refraction, diffraction and interference, but they can be time consuming to set up and take down. This Mini Ripple Tank addresses these issues by providing a completely self-contained device, requiring no set-up apart from the addition of water. Illumination is from a high intensity built-in LED which can automatically set the strobe frequency to be in sync with the waves to give perfectly stationary images, or switched to allow the user independent control of the wave and strobe frequencies giving the impression of wave motion across the viewing screen. 

Great for small groups! It is small and portable, making it great for small group demonstrations or stations.
