Diffuse and Specular Reflections (Lab 9 of 23)

This video from Laser-Tec is part of a series of light and optics experiments. In this lab, participants explore the difference between specular and diffuse reflections, identify skin and ocular hazards associated with the specular reflections of a laser beam, and identify protection and safety measures for operating a laser. Equipment includes a red laser diode module, frosted incandescent light bulb, and two index cards. The video recording runs 8:12 minutes in length.
