Section 10.3: Exploring Changing Well Width




Choose a state:


Choose a width:

Please wait for the animation to completely load.

The animation shows position-space energy eigenfunctions in an infinite square well. The width, L, of the well can be changed as can the quantum number, n. Restart.

  1. What is the value of ħ2/2m in this animation? How do you know?
  2. For what value of the width of the well can you get En = n2?
  3. How does the energy of a given state depend on the well width? Use the curviness of the energy eigenfunction to support your answer.
