Fundamentals of Light and Lasers: The Spectrum of Colored Light

This lab activity, presented by John Chamberlain, examines the spectrum of colored light as it passes through a diffraction grating. In this four-minute video, Chamberlain demonstrates the use of color filters, stands, a flashlight, and the diffraction grating to identify and modify ranges of color in the spectrum. Students can then use this information to investigate the spectrum on their own. This lab, 1-1C, is the third in a series of 20 available on the Fundamentals of Light and Lasers. 

These videos were created as a supplement to the Fundamentals of Light and Lasers curriculum available through OP-TEC, but can be used independently to guide lab activities related to this topic.
