This applet plots the probability densities in the stationary states ynlm(x,y,z) of the hydrogen atom in nonrelativistic quantum mechanics. (n is the principal quantum number, l is related to the total angular momentum, and m is the z-component of the angular momentum in units of Planck's constant.) The applet shows the probability density |ynlm(x,0,z)|2 in a plane containing the z axis; the full spatial probability density may be visualized by (mentally) rotating this around the z axis.
