2-D Rectangular Square Well 1.5

This java applet is a quantum mechanics simulation that shows the behavior of a particle in a two-dimensional rectangular square well ("particle in a box").

In the center of the applet, you will see a plot of the wave function. The brightness indicates the magnitude and the color indicate the phase. At the bottom of the screen is a set of phasors showing the magnitude and phase of some of the possible states.

You may select a single state by picking one of the phasors at the bottom and double-clicking on it. Or, you may click on the phasor and drag its value to modify the magnitude and phase. In this way, you can create a combination of states.
