How fast can light travel in one year?
300000 km/second
How fast does light travel through copper?
Copper is opaque to light - light can not travel though it.
How fast does light travel per foot?
the speed of light
How fast would it take to travel one light year at the speed of light?
It would take light one year to travel one light year. (The answer comes from the definition of a light year.) We cannot go that fast; only light can. Relativity confuses matters slightly. If you travel one light year at the speed of light, an outside observer would say it took you one year. You yourself would say the trip was instantaneous. Since, as noted above, you can't possibly go that fast, if we say that you were merely very very close to the speed of light, you'd say it took a much shorter time than one year; the exact length would depend on exactly how fast you were going. (Even more confusing: by your measurements), you wouldn't have gone a light year at all, but some shorter distance. Again, exactly how short depends on how fast you were going.)
How fast can light travel in one year is it about 6 trillion miles?
Yes, it is - in vacuum.
What travel fast light or sound in the universe?
light travels faster.
Some fast do light rays travel?
Yes, they travel some fast!
What is darkness and how fast does it travel?
Darkness is the absence of light and will therefore travel at the speed of light (6x108m/s)
How do sound waves travel compared to light waves?
light waves fast
Can light travel as fast as sound?
no from what i have learned light travels faster then sound
The speed of light indicates how fast light can travel in a vacuum?
Yes ... in a vacuum.
What does light have to do with science?
Light's contribution to Science was when the scientists realised how fast light can travel around the world.
