Optics is probably one on the most exciting topics in physics. However, it also contains some of the
\nless understood phenomena by students\u2014the light spectra obtained from the diffraction of light. The
\nexperimental study of light spectra for studying radiating bodies, usually requests sophisticated
\nand expensive equipment that is not normaly affordable for schools, and only a few teachers know how
\nto measure the wavelength of light in a spectrum. In this work we present a simple and inexpensive
\nsetup, with enough accuracy for measuring light spectra to be used both in physics and chemistry
\nclasses. We show how freeware software Tracker , commonly used for teaching mechanics, can serve to
\nmeasure wavelengths with about 2\u2009nm of resolution. Several approaches to the calibration of
\ndifferent setups are also provided, depending on the degree of accuracy demanded.<\/p>\n","protected":false},"excerpt":{"rendered":"
