Answer: The speed of light was determined through experimentation, such as the timing of moons passing behind Jupiter. Many formulas are based upon the speed of light, but that number had to be determined beforehand.
Light travels 299,792,458 meters per second (or 186,282.397 miles per second in a vacuum.
Answer: Yes, the speed of light can be deduced from the electrical properties of empty space. However, in practice it is more accurate to measure the speed of light.

Who are the scientists who calculated the speed of light?
Ole Romer
Does Light have a speed or a velocity speed of light or velocity of light?
Light travels at the speed of light. There is no general velocity of light because velocity is a vector quantity, it also contains a direction and there is no preferred direction for light rays in general. Another answer: The speed of light has been calculated to be 186,000 miles per second.
What is the speed of light in machs?
if calculated it right it is mach 882352.94 at sea level
Who contributed to the evidence of electromagnetic waves and their link to light?
James Clerk Maxwell derived the existence of electromagnetic waves. Due to its speed (as calculated from his equations), which is the speed of light, he concluded that light is probably also an electromagnetic wave. This was confirmed later.
Is it light speed or the speed of light?
speed of light I think well it sounds right:)
Who are the scientists who calculated the speed of light?
Ole Romer
How did physicist calculated the prise measurement of the speed of light?
Stop watch and a light switch
Ho calculated the speed of light mathematically?
James Clerk-Maxwell did.

When velocity of light was discovered?
In 1728, James Bradley deduced that starlight falling on the Earth should appear to come from a slight angle, which could be calculated by comparing the speed of the Earth in its orbit to the speed of light. This "aberration of light", as it is called, was observed to be about 1/200 of a degree. Bradley calculated the speed of light as about 298,000 km/s (186,000 mi/s).
What characteristics of the electromagnetic waves predicted by maxwells theory led him to suggest that light might be electromagnetic wave?
The speed calculated for such waves, which happened to be precisely the speed of light.
Who is the scientist use the light year to measure the speed of light?
It doesn't work that way. The light-year is not used to measure the speed of light. It works the other way round: First, the speed of light is determined through other methods, then the distance called a light-year is calculated based on that measurements.
What is the light frequency?
The frequency of a wave of light is given by speed of light/wavelength, or by energy/Planck's constant.If you know the frequency or the energy associated with the light, it is easily calculated.

What is a material's index of refraction?
It is the ratio between the speed of light in a vacuum, and the speed of light in the material. The angle at which light is refracted is related to the index of refraction, and can be calculated using Snell's Law.
