A student is carrying out an experiment similar to Fizeau's experiment to measure the speedof light. He sets up a mirror on one headland and a laser and photosensor on another,3.20 km away, positioned behind a toothed wheel, as shown. The laser light reflects off themirror, passes between the teeth of the wheel and reaches the photosensor. The gaps betweenthe teeth on the wheel are 6.00 mm wide.Laser and photosensortoothed wheel6.00 mm gaps200 ms¹mirror3.20 kmDuring the night, the angular velocity of the toothed wheel is gradually increased from zerountil the photosensor records no light. The student measures the speed of the teeth on thewheel to be 200 ms¹ at this point. Using this information, what should the student calculatethe velocity of light to be?

Three sheets of plastic have unknown indices of refraction. Sheet 1 is placed on top of sheet 2, and a laser beam is directed onto the sheets from above so that it strikes the interface at an angle of 26.6deg with the normal. The refracted beam in sheet 2 makes an angle of 31.4deg with the normal. The experiment is repeated with sheet 3 on top of sheet 2 and, with the same angle of incidence, the refracted beam makes an angle of 36.8deg with the normal. If the experiment is repeated again with sheet 1 on top of sheet 3, what is the expected angle of refraction in sheet 3? Assume the same angle of incidence.
