Fundamentals of Light and Lasers: Building an Inexpensive Spectometer

This lab activity, presented by John Chamberlain, demonstrates the use of an inexpensive spectrometer. The four-minute shows the process of examining the wavelengths of light from three different sources: incandescent, florescent, and neon lights. Questions for students about the spectrum are included. This lab, 1-2C, is the seventh 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.
