Astronomy
Three Hands-On
Activities Illustrating Spectra
In this set of activities, the tricky concept of spectroscopy is addressed. They include a general investigation of the formation of spectral features, a detailed analysis of the spectrum of the hydrogen atom, and the dispersal of the spectrum of a laser. Laboratory exercises and demonstrations that teachers and students can readily undertake given equipment likely to be available in most school systems.
