- Function and Applications:
With the Speed of Light Meter you can measure the velocity of light in air and in other transparent media and additionally you can determine the distance.
- Benefits:
Measuring the speed of light, as well as distances, with only one device all thanks to state-of-the-art digital measuring technology
The unit is convincing by a quick set-up and a need of minimum adjustment
The speed of light can be measured with an accuracy in air of +/- 2%
Measurements can be performed with or without an oscilloscope
Due to the integrated display of all of the relevant measurement quantities (ƒ, Δφ, Δt, Δx) the unit is of special interest for student and teacher experiments
Distance measurements can be performed with the same device
