The Ripple Tank Model for Teachers allows instructors to simulate 2D wave interference. A ripple tank is a shallow glass tank of water used to demonstrate the basic properties of waves. The tank is usually illuminated from above, so that the light shines through the water. The ripples on the water show up as shadows on the screen underneath the tank. In the default visualization the wave crests and troughs are shown as red and blue. Users can change the number of sources, their amplitude and phase, and other parameters. Selecting student mode repackages the modified simulation into a stand-alone jar file with fewer options for classroom use.
The Ripple Tank Model for Teachers was created using the Easy Java Simulations (EJS) modeling tool. It is distributed as a ready-to-run (compiled) Java archive. Double clicking the ejs_waves_teacher_RippleTank.jar file will run the program if Java is installed.
Please note that this resource requires at least version 1.6 of Java (JRE).
