Product Description

Speed of Light Lab Kit

This Speed of Light Lab Kit, allows students to easily and accurately measure the speed of light! As powerful and accurate as it is simple, this kit was designed for teaching and learning about how to calculate, measure and understand the speed of light. 

Such was not the case for many centuries. The famed Galileo - after he attempted to measure the speed of light with an unlikely arrangement of lanterns and flags on tall towers - decided that light must travel at infinite speed. Later, Armande Fizeau used an elaborate mechanism with mirrors, lens and a huge rotating cogwheel to determine if the speed of light was, in fact, not infinite. He got close. After many years we now know light does not travel at infinite speed, but rather 299,792.4562 meters per second in a vacuum.

With the proper combination of electronics, electro-optics and fiber optics this once-difficult measurement is simple and can be conducted in any lab or classroom. All that's needed is a 60 x 100cm table, 110 VAC electrical power, oscilloscope  and the Speed of Light Lab Kit.

To conduct the speed of light experiment, first apply 110 VAC power to the oscilloscope and Speed of Light Lab Kit, then connect oscilloscope probes to apparatus test points. After calibration, the oscilloscope monitors the reference and delayed pulses, the time delay is measured and the speed of light calculated. 

An integral part of the Speed of Light Lab Kit is an easily understood full-color, often lighthearted manual. It begins by tracing the early steps of technical pioneers in their quest to understand light. The manual also includes detailed step-by-step set-up and measurement instructions and examples with equations for calculating the speed of light.
