Speed of Light/Receiver Kit

For years after lasers were invented they usually were considered only a novelty. People often commented, after seeing a laser beam for the first time, "Pretty, but what's it good for?" This kit makes the most of your modulated laser to demonstrate functions such as: - Transmitting/receiving an audio signal - Speed of light measurement - B/W video receiver transmission/detection The principle employed in this kit to measure the speed of light is similar to that used by Newcomb in 1880 and Michelson in 1924. In operation, the laser beam is split into two portions. Your instruction manual contains detailed instructions and diagrams describing equipment set-up, as well as ha historical journey into efforts to measure the speed of light. This is a great opportunity to learn not only about technology, but also the very human history behind it. Included in the kit are an optical beam splitter, first surface mirror, two converging lenses, optics mounts, microphone, electronic control box with 2-channel receiver and 1 MHz oscillator, 110 VAC-to-DC power adapter, optics table and step-by-step instruction book. Not included but required for operation are a modulated laser, video camera and monitor, and a dual-channel 40 MHz oscilloscope.
