Problem 11.3: Determine the energy bands and gaps for a periodic potential

Please wait for the animation to completely load.

Shown in the graph is the transcendental equation describing the bound-state energy levels of a series of finite square wells. The teal lines represent the range of one side of the equation and the red curve represents the other side of the equation. In the animation, ħ = 2m = 1.  What are the allowed energies for the system represented by this transcendental equation?  Restart.
