SUMMARY
The Fizeau Toothed Wheel Experiment calculates the speed of light using the formula derived from the number of teeth on the wheel, the revolutions per second, and the distance between the mirror and the toothed wheel. Specifically, the time taken for light to travel to the mirror and back is determined by the wheel's rotation, which is calculated as the number of teeth divided by the revolutions per second. This experiment effectively demonstrates the relationship between distance, time, and speed, confirming that speed equals distance divided by time.
