Photon Emission and Absorption

These are the notes from last year, but they will do until I get this year's up. These cover today AND yesterday.

Homework:

Find the frequency of the photon emitted or absorbed when an electron:
1. "Falls" from E=15 to E=13. Was this photon emitted or absorbed?
2. "Jumps" from E=10 to E=15. Was this photon emitted or absorbed?
Remember that you can leave Planck's Constant as "h" if you wish.
