Question 2
In Fizeau's experiment to measure the speed of light, the wheel has 475 notches and rotates with a speed of 40.0 rev/sec. Light passing through one notch travels to the mirror and back just in time to pass through the next notch.
If the distance between the wheel and the mirror is 7890 m, what is the speed of light measured by this experiment? A) 3.00 108 m/s
B) 3.00 10-8 m/s
C) 3.22 108 m/s
D) 3.22 10-8 m/s
E) 2.25 108 m/s
