Computer-generated visualization of a wave function that is a solution of the Schrödinger equation for the hydrogen atom. The wave function belongs to a stationary state with quantum numbers n=12 (main quantum number), l=6 (angular momentum quantum number), and m=2 (magnetic quantum number). The wave function is a complex-valued function, the color represents the phase and the isosurface, resp. the density plot in the x-z plane represents the absolute value.
