What is the exact speed of light miles per second?
186,282.397 miles per second.
What exactly is speed of light in miles and kilometers?
The speed of light, in vacuum, is exactly 299,792,458 metres per second or 299,792.458 kilometres per second. The values are exact because this is how a metre is defined. The relationship between a kilometre and a mile is not exact, so it is not possible to give an exact figure for the speed in miles. It is approximately 186,282 miles per second.
An electric field travels over a wire at what speed?
almost the speed of light which is 300 000 kmps i am not sure of an exact figure but i know its close to light speed also the amp-age on the circuit can affect it
How does the speed of a radio compare to the speed of visible light?
Radio waves and light are the same exact physical phenomenon, and differ only in their wavelength (frequency). Their speeds are identical.
IS electromagnetic waves travel faster than speed of light?
Electromagnetic waves are, by definition, light. So they travel at the exact same speed as light.Also, a "Do" would be appropriate here, instead of an "IS".
What is the exact speed measurement of light?
The speed of light in vacuum is 299,792,458 meters (186,282 miles) per second.
What is a exact speed of light in a vacuum?
The speed of light is 299 792 458 m s-1.This is one of the very few exact physical constants; it is so by definition.This enables the meter to be determined by it and the second.
What is the exert speed of light?
The exact speed of light in vacuum is 299,792,458 meters per second. It's something different in every different material stuff.

How does fast light travel?
The speed of light is 299,792,458 meters per second through vacuum. It's somewhat lessin any kind of material stuff ... the exact speed depends on what stuff it's moving through.The speed of light in a vacuum is 300,000 kilometers/second.
What happens to speed of light from vacuum to glass?
The speed of light is greatest in vacuum, and somewhat less in any material medium. The exact number depends on the individual material. They're all different.
What is the exact speed of light in numbers?
Exactly 299,792,458 meters per second is.
