Teaching Diffraction with Hands-On Optical Spectrometry
Fischer, Robert
Physics Education, v47 n5 p603-607 Sep 2012
Although the observation of optical spectra is common practice in physics classes, students are usually limited to a passive, qualitative observation of nice colours. This paper discusses a diffraction-based spectrometer that allows students to take quantitative measurements of spectral bands. Students can build it within minutes from generic low-cost materials. The spectrometer's simple, didactic design allows students to fully comprehend the underlying physical concepts and to engage in a discussion of measurement errors and uncertainties. (Contains 4 figures.)
