Description

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.

Don’t waste your money or time!
Color: White, Size: Standard - 4 Panel
Don’t waste your money. The instructions make no sense and the metal poles are either sized wrong for the product or screw holes are incorrectly placed, but no two poles matched in size and placement making it impossible to put this together without the panels being warped. No matter how I tried to switch the poles to see if I had them wrong, they always turned out warped and incorrectly fit. I finally gave up and threw everything out - I wasted $50 on this junk and because I didn’t try to put it together immediately after I bought it, it is way too late for a refund. Lesson learned!

Sturdiness
Color: Black, Size: Standard - 4 Panel
Not so sturdy. It worked well for its intended job, but, it has to be secured to the floor for long term use.

Wobbly but Usable
Color: Grey, Size: Standard - 4 Panel
A bit wobbly, but good enough for the price when you need a solid background for remote work calls.

Nice and easy to assemble
Color: Black, Size: Standard - 4 Panel
I absolutely love this 4-panel room divider! It was super easy to assemble — I had it set up in just a few minutes. The material isn’t too see-through, which gives just the right amount of privacy while still letting some light through. It does exactly what I needed it to do and looks so clean and sleek in my space. Perfect balance of style and function — highly recommend!
