The "official" speed of light in a vacuum is 299,792,458 metres per second
So in a millisecond - which is one-thousandth of a second - it will travel 299,792.458 metres.
The Imperial equivalent of that is 186.2824 miles, or 186 miles, 495 yards, 5 inches.
Yes ... in a vacuum.
About 1100 feet per second, which is the speed of sound.
There are 1000 milliseconds in a second, so 300 milliseconds is 300/1000 or 0.3 seconds.
Radio waves travel at the speed of light which, in a vacuum, is about 3 x 108 meters per second.
Light will not travel into silver.
Yes, they travel some fast!
Copper is opaque to light - light can not travel though it.
151.52 milliseconds.

it can travel from 380nm [nanometres] to 740nm
How many hours does it take to get to 4.5 billion km
The speed of eyesight varies depending on factors such as the speed of light and the time it takes for signals to travel from the eyes to the brain. Light travels at approximately 186,282 miles per second, but the brain processes visual information in a matter of milliseconds. Overall, the speed of eyesight is incredibly fast and allows for near real-time perception of the environment.
Darkness is the absence of light and will therefore travel at the speed of light (6x108m/s)
10 to 25 milliseconds
