How long would it take light from the moon to reach earth?

Question

(the distance from the earth to the moon is approximately 240,000 miles.)

Answer 1

The moon produces no light on its own. It acts as a giant mirror and simply reflects the suns light.

Answer 2

The Moon at 240,000 miles distance, light travelling at 186,000miles per second, reaches Earth in 1.3seconds.

Answer 3

I think it would take about one second, thats what I heard and considering how fast light moves... it's probably around that long.

Answer 4

299 792 458 m / s

386242560 metres to the moon (approx)

light travels at:

299 792 458 m / s

so  386242560 / 299 792 458  = 1.288 seconds

Answer 5

To calculate the time taken for light tot travel from the moon to the earth, convert the distance in miles to metres, as follows: -

240,000 x 1609 = 386160000 m

Then divide the distance in metres by the speed of light, thus: -

t = 386160000 / 299792458

t = 1.29 seconds (rounded to 2 DP)

Since the distance of 240,000 miles, to the moon, is approximate, then it is only reasonable to say that it takes about 1 second for light to reach the earth from the moon.  

Answer 6

the moon dose not give off light it reflects it
