It would take (10 divided by 30,000,000,000) seconds to travel 10 cms, which is 0.000000000333333 of a second (approximately!) In nanoseconds this is 1/3rd of a nanosecond.
For all practical purposes, for such a small distance, one could consider that the beam of light (in space) would travel that distance almost in an instant. It's that fast!
f. all travel at the same velocity. In a vacuum, all colors of light travel at the same speed, which is approximately 299,792 kilometers per second. This speed is known as the speed of light.
The velocity of light in a vacuum is approximately 299,792 kilometers per second (or about 186,282 miles per second). This speed is constant and is the fastest speed at which information can travel in the universe, according to the theory of relativity by Albert Einstein.
All colors of light travel with the same speed.
The velocity of light coming from a cars lights will be the speed of light C in the substance in front of the lights. It wont be the speed of light+the speed of the car however.
Neutrinos do not travel at the speed of light, but they do move very close to the speed of light.

c is a constant variable commonly known as "the speed of light", but more correctly the velocity of the speed of light ought to be called "the velocity of the speed of electromagnetic wave interactions". And it is precisely 299,792,458 meters per second.
The velocity of light coming from a cars lights will be the speed of light C in the substance in front of the lights. It wont be the speed of light+the speed of the car however.
There are different speeds involved.* An electrical signal travels about 200,000 km/second in a wire - about 2/3 of the so-called "speed of light". * The drift velocity (average velocity) is typically less than a millimeter per second. * Individual electrons travel at a significant fraction of the speed of light.
Neutrinos do not travel at the speed of light, but they do move very close to the speed of light.
"Travel velocity could have two definitions. Travel Velocity is a web page that advertises and sells discounted airline, hotel, and other travel deals. Secondly, a general reference to travel velocity is the speed at which sound or light travels in relation Physics."
Light second
The speed of light in a vacuum, approximately 299,792 kilometers per second (186,282 miles per second), is considered the highest possible velocity for electromagnetic phenomena. Nothing with mass can travel at or faster than this speed according to the theory of relativity.
Light travels at a constant velocity, no matter what time it is given to travel. Light would travel at exactly 299,792,458 ms-1 in five minutes, but only in a vacuum.
