Fundamentals of Light and Lasers: Interference and Diffraction: Pinhole

This lab activity, presented by John Chamberlain, is one of four on the topic of interference and diffraction. In this 10-minute video, Chamberlain demonstrates the measurement of the Fraunhofer diffraction of a laser beam passing through a pinhole and the diameter of the airy disk produced as the light passes through the pinhole. This lab, 1-5B, 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.
