If the optical path length between mr and mo is d, then the light, travelling at a speed c, takes a time t 2d c between reflections at mr, so that if the mirror is rotating at an angular velocity , then × t 2 and thus (1) d c x 4 d c the determination of c thus reduces to the measurement of two fixed distances, a variable angular Web designated by the letter c , the speed of light in empty space is 299,793 km/s (186,282 miles/sec) so that light takes only 1.3 sec to travel from the moon to the earth. Speed of light = distance time.
