... Turn on the incandescent light and hold up the Glo-Doodler in front of it. Ask students to describe how this spectrum is different from that of the bulb by itself or from the fluorescent bulb. (The Glo-Doodler absorbs certain wavelengths, which show as black bands in the spectrum.) Think of a safe w ...
