crisscrossing Science Episode 060: Lightbulbs
In this episode, Mike Crosser (professor of physics at Linfield College) and Chad Tillberg (professor of biology at Linfield College) explain where light comes from "when a mommy photon and a daddy photon love each other very much. . . ." In reality, light is a way that atomic particles are able to exchange energy. All sources of light are derived from this simple fact. From this idea, Crosser and Tillberg discuss how different light bulbs work and discuss pros and cons to different types.
