1 The Schroedinger Applet

 The Schroedinger applet, shown below, has been initialized with the settings necessary to calculate the ground state of a one-dimensional harmonic oscillator. Click the Solve button and the plotting window will display the wave function in red and the potential in blue, with a green horizontal line at the energy value. (The first calculation may take longer than subsequent ones since the applet may need to download some Java class files.) The scale of the graph is set so that the maximum value of the unnormalized wave function is 1.0. The value of the energy and potential curves is obtained by multiplying the graph value by the Vscale value given in the left panel.
