Are you asking when the speed of light was first estimated, or are you asking when the speed of light was first actually measured?
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.
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.
Aristotle did not directly contribute to the discovery of the speed of light. The speed of light was first measured by Ole Roemer in the 17th century using observations of Jupiter's moon Io, and later refined by other scientists. Aristotle's work primarily focused on natural philosophy and did not extend to the study of light and its speed.
The refractive index of a material is calculated by dividing the speed of light in a vacuum by the speed of light in that material. It indicates how much the speed of light is reduced when passing through the material, providing information about how light bends as it enters the material.

The frequency of 850nm light is approximately 353 THz (terahertz). This is calculated using the speed of light (3 x 10^8 m/s) and the formula frequency = speed of light / wavelength.
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.
Index of refraction can be calculated using the formula n = c/v, where n is the index of refraction, c is the speed of light in a vacuum, and v is the speed of light in the medium. Just divide the speed of light in a vacuum by the speed of light in the medium to find the index of refraction for that medium.

No. We already know a good deal about the speed of light. Scientists study other galxies to learn how galaxies work.
It's the fastest speed anyone can prove exists. Any speeds in excess of light speed are still just theory. Some scientists believe it is the fastest speed that will ever be achievable.( a cosmic speed limit.)
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.
