WebDec 23, 2024 · A light-year is a measurement of distance and not time ... Because of the finite speed of light, it can take more than 20 minutes to send a signal to the Curiosity rover on Mars. Webrequired for the light beam to travel a given distance to the fixed mirror. By taking measurements relating the displacement of the two light beams and the angular speed of the rotating mirror, the speed of light was found to be (3.09±0.204)x108 m/s, which is within 2.7% of the defined value for the speed of light. 1 Introduction
