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 first successful attempt to measure the speed of light was in 1676 by Danish astronomer Ole Rømer. He estimated the speed of light by observing the eclipses of Jupiter's moon Io.

How did the Greeks measure the speed of light?
I don't believe there was any serious attempt to measure the speed of light before Galileo. That was a couple of millennia after the golden age of the Greek philosopher 'scientists', who, I believe, assumed the transfer of light to be instantaneous, and the perception of distant events to be simultaneous with the event.
Who are the scientists who calculated the speed of light?
Ole Romer
How do you measure the speed of light?
by getting boners.
1600s Galileo attempted to measure the speed of light using blank?
Galileo attempted to measure the speed of light using lanterns positioned at known distances and observing the time it took for light to travel between them. He would uncover the lanterns simultaneously and use a telescope to try and detect any delay in the light reaching his eyes. However, his methods were not sensitive enough to accurately measure the speed of light.
How many g's is the speed of light?
speed of light is constant velocity and does not accelerate so there is no g force

Who try to measure the speed of light?
Roemer was the first to measure the speed of light.
How do scientists measure distance in space?
Scientists measure distances in space using a variety of methods, including parallax, radar ranging, and analyzing the light emitted by objects in space. These techniques allow scientists to calculate distances based on the speed of light and the time it takes for light to travel between objects.
Why do you measure distance in the universe in light years?
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.)
What can scientist measure when light rays are emmitted by a moving source?
When light rays are emitted by a moving source, scientists can measure the Doppler effect, which is the change in frequency or wavelength of a wave in relation to an observer moving relative to the source. By analyzing the Doppler effect, scientists can determine the velocity and direction of the moving source.
What is use by scientist to measure the distance light travel in one year?
Scientists don't measure the distance light travels in one year. They calculate it by measuring the speed of light. The speed is 300,000,000 meters/sec. and can be measured in the laboratory with a rotating mirror apparatus. To get the distance traveled by light in one year you multiply the speed (above) by the number of seconds in a year. The answer will come out in meters and is also called one light year.

What does an anemometer help scientists measure?
An anemometer measures wind speed. Check your spelling.
Does a megaphone measure light and speed?
No, a megaphone is a device used to amplify sound, particularly human speech. It does not measure light or speed.
How do you measure the speed of light?

When light waves are emitted by a moving source scientists can measure?
the change in frequency of the waves, which is known as the Doppler effect. By observing this frequency shift, scientists can determine the speed and direction of the moving source. This phenomenon is commonly used in various fields like astronomy, radar technology, and medical imaging.
