Use the following information to answer the next question. One accurate method to measure the speed of light is illustrated below. When the 8-sided mirror is stationary, light from the source reflects from surface 1, travels to the stationary mirror, reflects from surface IV, travels back to the 8-sided mirror, reflects from surface III, and is incident on the detector. Light source Stationary mirror IV III -17.5km. 8-sided rotating mirror Light detector As the 8-sided mirror begins to rotate, the light does not follow the path illustrated. Eventually, as the frequency of rotation of the mirror increases, a series of light pulses follow the path illustrated. 5. The minimum frequency at which the 8-sided mirror must rotate so that a pulse of light follows the path illustrated is A. 5.36 × 10² Hz B. 1.07 × 10¹ Hz C. 4.29 × 10³ Hz D. 3.43 × 10¹ Hz
