Please wait for the animation to completely load.
Shown are both an infinite and a finite square well with L = 2 (from x = −1 to x = 1) to which you can add a symmetric potential energy barrier or well from from x = −0.5 to x = 0.5. Use the slider to change the size of this addition. To see the other bound states, simply click-drag in the energy level diagram on the left to select a level. The selected level will turn red. For the animation we have set: ħ = 2m = 1. Answer the following for both the infinite and finite well:
