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.

How do you measure the speed of light?
by getting boners.
When did scientists attempt to measure the speed of light?
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.
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
Why did early experimental attempts to measure the speed of light fail?
If you want to measure the speed of something, you first have to recall that speed is (distance traveled) divided by (time to travel the distance), and then you realize that you have to measure the distance it travels and the time it takes to travel that distance. If it happens to be the speed of light, then you immediately have a serious problem. The speed of light is so great that ... -- If you pick a distance that's easy to measure, then the time is impossibly short. For example, if you pick ten miles, then you have to accurately measure 0.00005368 of one second, which is pretty tough. -- If you pick a time that's easy to measure, then the distance is ridiculously long. For example, if you pick 0.1 second, then you have to accurately measure 18,628.2 miles, which is enormously tough. Both of these methods are theoretically and technically perfect, and completely impossible to actually use for the speed of light. You have to invent whole new clever ways to measure speed.
Who try to measure the speed of light?
Roemer was the first to measure the speed of light.
How would you measure the speed of light?
Light years
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?
by getting boners.
Why it harder to measure the the speed of light than it is to measure the speed of sund?
Roughly speaking, light moves about a million times faster than sound in air.
Which is faster and why speed or light?
Light is faster because speed does not move. Speed is a measure of the rate of movement but, in itself, it does not move - at all!
How long is the speed of light?
The speed of light isn't a distance so it has no length it is a measure of speed, which is roughly 186000 miles per second.
The speed of light measure?
Light travels at about 186,000 miles per second
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.

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.

Does velocity affect the speed of light?
The speed of light is always the same, as long as the light stays in vacuum or in the material substance it's in. The speed of the source generating the light, or the speed of the person who's measuring the light, has no effect on the light's speed. It will always measure the same number. That means: -- If a rocket is in space, flying toward you at half the speed of light, and the astronaut aboard shines a flashlight at you, and -- If you strap a jet-pack on your back and fly toward the rocket at half the speed of light, and -- If you measure the speed of the light from his flashlight as it shines past you, -- You'll measure the same speed of light as if you and the astronaut were both standing still. It can't be . . . But it is. It's been confirmed in thousands of experiments during the past 100 years.
