Laser Speed of Light Project with laser 0.8 mW / Class II
Easily set-up project for measuring the speed of light using a laser

In the last few years, lasers have become invaluable tools in thousands of industrial, scientific, medical and communications applications. This project, in several individual experiments, demonstrates a laser's unique ability to perform a variety of tests with deceptive ease.

The modulated laser included with this kit can also be utilized for hundreds of other classroom and real-life projects. The instruction manual contains detailed instructions and diagrams that describe equipment set-up, as well as a historical journey into efforts to measure the speed of light. This is a great opportunity to learn not only about new technology, but also the very human history behind it.

Not included but required for operation is a dual-channel 40 MHz oscilloscope.

Included in the kit are: .8 mW diode laser, optical beam splitter, first- surface mirror, converging lens, optics mounts, electronic control/receiver box with 2-channel receiver and 1 MHz oscillator, 110 VAC-to-DC power adapter, optics table, and step-by-step instruction book.

Activities include:

  • Measuring the speed of light
