Are you asking when the speed of light was first estimated, or are you asking when the speed of light was first actually measured?
The speed of light was first measured in 1676 by Danish astronomer Ole Rømer using observations of the moons of Jupiter. Rømer's work provided the first quantitative estimate of the speed of light.
The speed of light is constant and does not change based on the material it passes through. However, when light enters a medium such as glass or water, its speed decreases due to interactions with the atoms in the material.
the light, light travels faster than speed :) ami
Olaus Rømer explained the apparent incorrect timing of the eclipses of the Jovian satellites by the speed of light.
The first estimation of the speed of light was based on observing the timing differences between the eclipses of Jupiter's moons as observed from Earth. This was done by Ole Rømer in 1676.
It was the Danish astronomer, Olaus Roemer, who, in 1676, first successfully measured the speed of light. His method was based on observations of the eclipses of the moons of Jupiter (by Jupiter).
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.
Roemer was the first to measure the speed of light.
No human has flown faster than the speed of light, as it is currently considered impossible based on our understanding of physics. The speed of light, approximately 299,792 kilometers per second, is the cosmic speed limit according to the theory of relativity.

The speed of light of different colors passing through the same medium remains the same. This is because the speed of light in a medium is constant and does not change based on the color of the light.
Nothing has ever gone faster than the speed of light.
Light years are based on the speed of light. This particular measurement, which is used to measure astronomical distances to celestial objects, is the distance that light can travel in one year.One light year is equal to:0.31 parsecs63241 AU9.461×1012 km9.461×1015 meters5.879x1012 miles
it was faucault who first measured the speed of light in water ......
A unit that is commonly used in astronomy is the light-year - the distance light travels in a year.
