The Ripple Tank FGE 12 is a set of tools that can be used to demonstrate or experiment concerning basic properties of wave such as reflection, refraction, difraction and interferention. Wave is simulated by generating wave on water surface. By the help of a lamp and a mirror, the water surface is reflected to the translucent screen then the wave shadow can be seen and observed.

This apparatus comprises a water tank which is supported by iron frame, a translucent screen, a mirror and a lamp and some other supporting tools.
