Question

How many meters does light travel in 1 nanosecond?

Answer 1

\[\frac{ 3x10^{8} meters}{ 1 \sec } * \frac{ 1.0x10^-9 seconds }{ 1 nanosecond }\]
This will give you meters per 1 nanosec

Answer 2

Thank 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 earth-moon distance ( ).How long after it is sent does it take such a laser beam (which is just a light beam) to return to earth?

Answer 3

So do they give you the distance from earth to moon?
