The CD ROM Spectroscope
Joachim Köppen Kiel/Strasbourg/Illkirch Spring 2007
These notes are a collection of experiments, explanations, and suggestions about using CDs, CDROMs, or DVDs as spectroscopes. They permit you to explore the spectrum of visible light, requiring little more than a few household items. You will be able to see that there is sodium, hydrogen and magnesium in the Sun, and to tell the nature of artifical light sources (street and office lamps).
