A Simple Demonstration of Absorption Spectra Using Tungsten Holiday Lights
Birriel, Jennifer J.
Astronomy Education Review, v8 n1 p010203-1-010203-5 2009
In a previous paper submitted to the Demonstrations section (Birriel 2008, "Astronomy Education Review," 7, 147), I discussed using commercially available incandescent light bulbs for the purpose of demonstrating absorption spectra in the classroom or laboratory. This demonstration solved a long-standing problem that many of astronomy instructors face trying to demonstrate how astronomical objects, such as stars, exhibit absorption spectra. In this paper, I briefly describe using a strand of tungsten holiday lights to demonstrate absorption spectra and discuss the advantages and disadvantages of using a holiday light strand versus the previously discussed, full-sized incandescent light bulbs. (Contains 2 figures.)
