The night is alive with lights whose spectra are different, intriguing, and beautiful.
Help your students learn how to tell them apart by equipping them with this combination holographic diffraction grating (spectroscope) and pocket-sized spectra chart. If you simply hold the grating up to your eye, you can view and identify mercury, metal halide, and sodium lights, as well as incandescent, fluorescent, and neon. The principle behind this spectroscope and chart is the same one that astronomers use to explore star composition.
