Question 2

French physicist Hippolyte Fizeau set up an experiment where he sent light through the gaps in the teeth of a rotating gear to a distant mirror, as shown in this figure. He measured the speed of the light when it bounced back from the mirror. If you performed a similar experiment, what value would you get for the speed of light if the distance to the mirror was 50 meters and you estimated that it took light 3  10-7 seconds to travel that distance and return? (See page 349 of your textbook for more on this experiment.)
 a. 6.6  108 meters/second.
  b. 3.3  108 meters/second.
  c. 1.7  108 meters/second.
  d. 3.0  108 meters/second.
  e. 2.997  108 meters/second.
