# How many times does light go around the Earth in one second?

equation used: time = distance/rate..... x seconds = (circumference of earth)/(speed of light).....

x = (4.00727E7 meters)/(3.00E8 meters per second)

x = .1335 seconds

.1335 seconds is how long it takes light to orbit earth once.

1/.1335 = 7.4

light travels around the earth ~7.4 times in one second.

Hope this helps

(Of course, light would never travel like this, except around a body with enough mass to curve space-time enough for light to be trapped in that orbit, though it would be a very unstable orbit and would eventually escape or fall spiralling).
