One Way Speed Of Light Based on Fizeau's Experiment

Authors: Eric Su

Based on Fizeau's experiment, the single cogwheel is replaced with two rotating disks to measure the one-way speed of light. A single slit is cut out in the radial direction on each disk for the light to pass through the disk. With both disks rotating at the same angular speed, the light can pass through both disks only if the second slit is in a different radial direction from the first slit. The light takes time to travel from the first disk to the second disk. With both slits rotating into the straight path of light, the one-way speed of light can be calculated from the distance between two disks, angular speed of the disks and the angular difference between two slits.
