## Periodic Potential Energy Wells Exercise #1

#### Please answer the following 2 questions
regarding the Physlet:

#### Description

Shown is the time-independent wave function for a particle in a
periodic potential energy function (a series of
finite square potential energy wells). You may change the state by click-dragging on the
energy-level diagram on the left. You may view the wave function or the
probability density.

#### Questions

- How many finite potential energy wells
are there?
- Why?
