Rainbow-Like Spectra with a CD: An Active-Learning Exercise
Planinsic, G.
Physics Teacher, v46 n6 p329-333 Sep 2008
Rainbow-like spectra, produced by reflexive diffraction of white light on a CD, offer a spectacular visual effect as well as an excellent classroom opportunity for students to learn how physics works. In this paper we show that building a coherent qualitative explanation can be a challenging task that requires students to combine gained knowledge with observations and explorations.
