*Please wait for the animation to completely load.*

Shown is a finite square well with *L* = 2 (from *x* = −1 to *x* =
1) to which you can add five potential energy steps:

V1 | V2 | V3 | V4 | V5 |

-1< x < -0.6 |
-0.6< x < -0.2 |
-0.2 < x < 0.2 |
0.2< x < 0.6 |
0.6 < x < 1 |

by using one of the five sliders 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.**
