: Could some one please tell me how long it takes light to travel from the moon to earth? : Thanks!

To figure out how long it takes the light to travel from the moon to the earth, Just look up the distance from the moon to the earth. Light travels at approximately 2.8 x 10^8 meters per second. (280000000 meters per second) Divide the distance by the speed of light, and that will give you the time (in seconds) it takes to reach earth. So, for example, if the moon was 560,000,000 meters from the earth, it would take approximately 2 seconds to reach the earth.
