Single Phase Square Ripple Tank, For Physics Lab, Power Source : Electric

The unit comprises a shallow tank with a scratch-resistant acrylic window on the bottom, supported by four adjustable legs. Two arms on the side hold an eccentric motor and bar assembly. The motor and bar assembly is suspended by springs so the vibration is not transmitted to the tank. 

 

A bright point light source is held overhead, which shines down through the water in the tank, and casts a shadow of the waves on the bench below.
