How was the speed of light first measured?

An early experiment to measure the speed of light was conducted by Ole Rømer, a Danish physicist, in 1676. Using a telescope, Ole observed the motions of Jupiter and one of its moons, Io. Noting discrepancies in the apparent period of Io’s orbit, Rømer calculated that light takes about 22 minutes to traverse the diameter of Earth’s orbit.

How did Fizeau calculate the speed of light?

Fizeau found that at a certain rate of rotation, the beam would pass through one gap in the wheel on the way out and the next gap on the way back. Knowing the distance to the mirror, the number of teeth on the wheel, and the rate of rotation, Fizeau was able to calculate the speed of light as 313,000,000 m/s.

What did Roemer discover about the speed of light?

Around 1676, Danish astronomer Ole Roemer became the first person to prove that light travels at a finite speed. He studied Jupiter’s moons and noted that their eclipses took place sooner than predicted when Earth was nearer to Jupiter and happened later when Earth was farther away from Jupiter.
