Lessons in Optics and Light in the Palm of Your Hand Colorfully illustrate additive and subtractive color mixing, color transmission, absorption and filtering of the different wavelengths of light with this set of primary and secondary color mixing paddles. You can also use the diffraction gratings in this set to view spectra from different light sources. Show students how a spectroscope, colored lights, and even polarized sunglasses work with the contents of this set.
