For 10 points name this constant, the rate at which a photon moves through empty space.
This constant, which is equal to one over the square root of epsilon naught times mu naught, divides the time-averaged intensity to yield the classical electromechanical radiation pressure. Hippolyte Fizeau used a spinning mirror apparatus to approximate this value with a time-of-flight technique. Relativistic energy and momentum tend to infinity approaching this value, which is equal to about 3.00 times ten-to-the-eighth meters per second.
