A laser beam takes 24 ms to travel from a rocket to the reflective surface of a planet and back to the rocket. how far is the rocket from this planet's surface?

Respuesta :

Answer:

3600 km

Explanation:

The light travels 2 times the distance  (there and back)

    speed of light = 3 x 10^8 m/s         24 ms = .024 s

         3 x 10^8 m/s * .024 s  = 2 d

               d = 3 600 000  meters     3600 km
