What is the speed at at which light travels?

Answer 1

Light speeds along at nearly 300,000 kilometers per second (or 299,792.458 km

to be exact). That is about 180,000 miles per second. Despite the extremely fast

speed of light, sunlight still needs more than eight minutes to reach the earth.

If one could turn off the light of the sun at this very instant, we would only

experience the total darkness eight minutes later. Sun and earth are separated

by what is called eight light minutes. If one thinks about it that myriads of stars

are millions of light YEARS from the earth, one gets some impression of how

immense the universe must be.
