Fundamentals of Light and Lasers: Lenses

This lab activity, presented by John Chamberlain, demonstrates the real images formed by converging lenses. In this 16-minute video, Chamberlain demonstrates the set up required for the activity, including a laser, mirror assemblies, and diverging lens, before showing how lenses can be used to focus images reflected by the laser light onto a target. Measurements are taken during the activity and used to demonstrate the calculation of predicted image distances and image size. This lab, 1-4D, 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
