5. In 1957, the U.S. Naval Research Laboratory conducted the first ever radar measurements of the distance from the Earth tolthe moon. By reflecting light from an Earth-based source off the moon and measuring the back-and-forth time of transit, scientists determined that the moon is approximately 3.84 x108 m from the Earth. Determine the time it takes light to travel from Earth to the moon and back.
