Section 7.5: Exploring Many Steps in Infinite and Finite Wells
Please wait for the animation to completely load.
Shown is an infinite square well with L = 2 (from x = −1 to x = 1) to which you can add five potential energy steps:
|-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. Given the following values for the potential energies,
what happens to the energy eigenfunction for small n and for large n? What happens to the energy spectrum? Once you have completed this exercise, explore Animation 2 which allows you to do something similar in a finite well.
