Investigates the interference of two waves. With this simulation, you can explore the interference pattern that results from the superposition of two sources of waves. The simulation models what happens with two speakers, emitting sound waves; with two oscillating bobbers in a water tank, producing water waves; or, with two light sources, so the interference is with two light waves.

In the simulation, red regions are areas where the net displacement is positive (such as when two peaks overlap) and blue regions are areas where the net displacement is negative (such as when two troughs overlap). In the black regions, the net displacement is zero, or close to zero.
