This lab activity, presented by John Chamberlain, demonstrates the determination of the minimum optical density of protective eye equipment needed for working with lasers. In the six-minute video, Chamberlain uses the example helium neon laser to show the process of calculating this optical density...
This lab activity, presented by John Chamberlain, introduces the law of reflection. In this six-minute video, Chamberlain uses a laser and a mirror to demonstrate reflection, and shows how to take readings, measurements, and make the calculations necessary to find the deviation angles and verify the...
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...
This lab activity, presented by John Chamberlain, focuses on the measurement of beam diameter and divergence from a laser. In this 14-minute video, Chamberlain demonstrates the set-up for the lab, including how to properly read a micrometer, and taking the necessary micrometer and power readings to...
This lab activity, presented by John Chamberlain, demonstrates techniques for optical alignment that will be useful to students in completing subsequent laboratory activities in this series. In the seven-minute video, Chamberlain shows both the rough and fine horizontal adjustment of a laser beam to...
This lab activity, presented by John Chamberlain, demonstrates the use of a photometer. In this six-minute video, Chamberlain uses the photometer to take readings of the sun's light as well as a reading of a helium neon laser beam. This three-part lab, 1-3E, is one in a series of 20 available on the...
This lab activity, presented by John Chamberlain, focuses on Malus' law and the angle between two polarizing filters. In this 8-minute video, Chamberlain demonstrates the set-up for the lab and the process of taking measurements with an analyzer in order to calculate predicted angles. This lab, ...
This lab activity, presented by John Chamberlain, teaches students to measure the power transmitted from a helium neon laser through various colored filters. In the 10-minute video, Chamberlain demonstrates the process by shining a laser through various colored filters, including blue, yellow,...
This lab activity, presented by John Chamberlain, examines the effects of prisms and lenses on light emitted from a laser. In first part of the twelve-minute video, Chamberlain demonstrates refraction of light through a prism, and the measurement and calculation of the angle of deviation produced...
This lab activity, presented by John Chamberlain, covers the the polarization of light using filters. In this four-minute video, Chamberlain demonstrates the use of a flashlight, stand, reflective surface, and polarizing filters (including one used as an analyzer) to examine planes of polarization. ...
