Wave Function Exploration #2

Please answer the  following 3 questions regarding the Physlet:

Description

Shown is a wave function to an unknown potential energy well.  Two questions test your understanding of the form of the wave function and its relationship with the potential. Restart.

Questions

  1. What energy state is depicted?

  2. The wave function changes "wavelength" and amplitude, what do these changes mean?

  3. How do you know?  You may consider a classical analogy.

  4. What does the potential energy well look like?
