Interference and Diffraction Through a Pinhole (Lab 19 of 23)

This video from Laser-Tec is part of a series of light and optics experiments. In this lab, participants explore interference and diffraction through a pinhole. Participants learn about the diffraction of light when it passes through a pinhole and calculate the radius of a central airy disc. Equipment includes a red laser diode module, laser holder, pinhole aperture, lens holder, measuring tape, a protractor, pencil, and white sheet of paper. The video recording runs 11:44 minutes in length.
