Yes I THINK.But he was only measuring from one mile so he got 0.000005 sec.

When was a telescope first used in space?
If you would consider a non visible light telecope, then the first such telescope was the gamma ray observatory OAO-1, which was set into orbit by NASA. For visible light it is was with the launch of Hubble by NASA in 1990.
Who are the famous scientist who contributed in motion?
Isaac Newton who discovered the Laws of Motion is one famous scientist - Another might be Einstein who discovered the Laws of reativity - showing that nothing can exceed the speed of light.
1600s Galileo attempted to measure the speed of light using blank?
In 1600 Galileo attempted to measure the speed of light using lanterns and shutters
How did Galileo attempt to measure the speed of light?
Galileo used two distantly-separated lanterns in his experiment. Galileo knew that light traveled very quickly, but did not appreciate how fast it really is. Standing on a peak at night with a shuttered lantern, he sent a colleague with another lantern to a peak some miles away, where the lights would still be visible to each other when opened. At a prearranged time, Galileo would uncover his lantern. The colleague, when he saw the light from Galileo's lantern, would uncover his own lantern, so that Galileo could then see it. The time between Galileo's uncovering and the time he saw the other lantern would be the time it took light for a round trip equal to twice the distance they were apart. The result, as would be expected today, was that the colleague saw the light practically as soon as Galileo uncovered it, and uncovered his own, which was then visible practically instantaneously to Galileo. No matter how far apart they were, the brief time lag was identical. Considering the reaction time by the assistant, and the time taken to open the lantern, Galileo reasoned that light traveled far too quickly to be measured.
Why did Galileo want to find out what the speed of light was?
oh Galilieo
Who was the scientist who discovered that heavy and light body of the same substance fall at the same speed?
Galileo I think.

What scientist invented the first light bulb?
This begs the question by assuming that it was invented by a scientist. Ask the question "who invented the light bulb" - you'll get a better answer.
Which scientist first discovered that white light is a mixture of a rainbow spectrum of light rays?
Newton
Who determined that the moon was not a source of light but reflected light?
Galileo

When was the light bulb officially invented?
The first electric light was made in 1800 by Humphry Davy, an English scientist.

What did the lamp do in Galileo's experiment?
it gave off light

What scientist found out about th colours in white light?
Newton was the first to examine the phenomenon thoroughly.
Why might a scientist use a light meter?
Scientist use a light meter to show how light in shining on a surface !
