Single Slit Interference
Double Slit Interference
Two Source Interference
The familiar ripple tank utilises ripples on a water surface to demonstrate the properties of waves. It consists of a shallow dish of water, with a transparent base. An electrically operated vibrator dips into the water surface and generates the ripples. Various objects may be placed in front of the source and single or double prongs may be attached to the dipper to simulate two source interference. There are three ripple tanks available; the Griffen, IEC and Pasco.
