Supplementary Material

Today's demonstrations: None.

Today's animations:

• Minispectroscopy interactive examples of spectra: http://mo-www.harvard.edu/Java/MiniSpectroscopy.html

• Standing waves animation: http://faraday.physics.utoronto.ca/IYearLab/Intros/StandingWaves/Flash/sta2fix.html

• What does a hydrogen atom look like? http://www.hydrogenlab.de/elektronium/HTML/einleitung_hauptseite_uk.html

• Hydrogen atom orbital viewer: http://www.falstad.com/qmatom/

• Using spectroscopy to test models of the hydrogen atom (open the Hydrogen Atom Model applet) - try this at home.
  Look at the predictions from all of the model. Make sure you run the experiments for awhile. Which model of the atom best predicts the experimental spectrum?
