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.

If a problem gives the number of teeth on the wheel, the revolutions per second of the wheel and the distance betweeb the mirror and the toothed wheel...what formula do youuse to solve for the speed of light??
 
Physics news on Phys.org
The teeth on the wheel and the revolutions per second will give you the time between time. If you have time and a distance the speed shoudl be pretty straight forward!

(hint, remember it's there and back again!)
