Interference and Diffraction Through a Slit (Lab 20 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 slit. Participants learn about the diffraction of light when it passes through a slit and calculate the width of a slit. Equipment includes a red laser diode module, laser holder, index card with a vertical slit, lens holder, measuring tape, protractors, a pencil, and white sheet of paper. The video recording runs 16:24 minutes in length.
