how to measure speed of laser light. You can determine the speed of light from how the time of the return pulse depends upon the distance traveled. What is the fastest thing we as the human race know of.

From these you can calculate speed values v X T. The plane mirror and the lens are both on. We then compare the measured speed of light with the measured speed of radio waves.
The speed of light is measured using a time-of-flight method over a distance of 20 cm using a high speed pulsed laser a beam splitter mirrors and fast detectors and oscilloscope.
One method for accurately measuring the distance to targets is through the use of a laser triangulation sensor. No seriously we dont measure the speed of light which always refers to the speed in a vacuum. Speed of Light measurement of c using a high-speed pulsed laser Overview A pulse of light from a laser travels to a mirror and returns. With the same oscilloscope plot.
