In this 8-minute video, Chamberlain demonstrates the set-up for the lab and the process of taking measurements with an analyzer in order to calculate predicted angles. This lab, 1-5C.1, is one 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
