Measure speed of light

How to measure speed of light?

Many experiments are at disposal to make this type of approximation. However an attempt at measurement can be made starting from a simple physics laboratory, it is called: the experiment Bertoïa

Material:

  1. a laser whose beam can traverse 100 meters
  2. two diodes photoelectric
  3. a storage oscilloscope
  4. a unit compensation separating available on any interferometer of Michelson
  5. and of the electric wires connecting a G.B.F. (generator low frequency) with the assembly
