How many different kinds of lights can you find around town at night? What is light pollution? Just punch out the 6 1/2" x 3" pocket-size grating/chart and check out the distant night lights. Learn how a diffraction grating works, verify its theoretical resolving power, and compare self-absorption in street lamp spectra to the Fraunhofer absorption spectra in the solar spectrum. Comes complete with lesson plan.
