Best ResponseYou've already chosen the best response.0Thank you, can you help me with this part: By bouncing laser beams off a reflector placed on our moon by the Apollo astronauts, astronomers can make very accurate measurements of the earthmoon distance ( ).How long after it is sent does it take such a laser beam (which is just a light beam) to return to earth?
