Speed of Light Apparatus AssembledWith 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 Apparatus. To conduct the speed of light experiment, first apply 110 VAC power to the oscilloscope and Speed of Light Apparatus, then connect oscilloscope probes to apparatus test points.

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 Apparatus.

To conduct the speed of light experiment, first apply 110 VAC power to the oscilloscope and Speed of Light Apparatus, 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 Apparatus 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.

  • All solid-state transmitter/receiver design
  • Low-voltage electronics operation
  • Fiber optic delay requires no optical alignment
  • Safe, visible LED light source
  • Quick set-up and measurement
  • Impact-resistant, protective enclosure
  • Rubber feet on chassis bottom for adhesion on smooth surfaces
  • Contained light beam is ideal for small areas
  • 28-page full-color manual with operating instructions and sample oscilloscope displays

The apparatus consists of an electronics circuit board in protective plastic enclosure; two fiber optic cables; test connections for all outputs and a 110 VAC-to-DC power adapter.

Adapters for 220 VAC will be furnished upon request.

The optical fibers terminate in simple cinch-collet connectors for easy assembly and efficient coupling.

Really nice!
Color: Brown
Nicely made. The wood has a lovely finish and rich color. The compartments have a softer bottom so you don’t have to worry about scratching your glasses or other surfaces. Great assortment of compartment sizes to help organize your items. Kicking myself for not getting one sooner.
