He didn't actually calculate the speed of light as the diameter of Earth's orbit was not well known in his day. But using his method with the knowledge of distances we have today, we get a value of approximately 301,204.8 km/s for the speed of light. This is only about 0.5% off the modern known value of the speed of light. 2015-11-13 The basic concept behind both events involves the speed of light (and all other forms of electromagnetic radiation), which scientists have thoroughly examined, and is now expressed as a constant value denoted in equations by the symbol c.Not truly a constant, but rather the maximum speed in a vacuum, the speed of light, which is almost 300,000 kilometers per second, can be manipulated by Rømer's determination of the speed of light was the demonstration in 1676 that light has a finite speed and so does not travel instantaneously. The discovery is usually attributed to Danish astronomer Ole Rømer, who was working at the Royal Observatory in Paris at the time. By timing the eclipses of the Jupiter moon Io, Rømer estimated that light would take about 22 minutes to travel a distance equal to the diameter of Earth's orbit around the Sun. This would give light a Ole Roemer and the Speed of Light.

Io. If the speed of light is finite, it will take light a certain time T to travel the distance d, and our measurement of the orbital period of Io will be off by the amount t. It will be shorter by t when Earth is moving towards Jupiter, and longer by t when Earth is moving away from Jupiter. 2015-04-20 · Ole Roemer, a Danish astronomer in the 17th century, stumbled upon the speed of light during timing observations of the emergence of Jupiter’s closest Galilean moon, Io, from behind the planet’s limb. The point wasn't really to measure the speed of light; Ole Romer is remembered because his was the first experimental evidence that light has a speed at all (contrary to the previous assumption that sight is instantaneous).

He stated it to be 220,000 km/s, which is not that different than the modern value of 299,792 km/s. Ole Rømer, the speed of light, the apparent period of Io, the Doppler effect, and the dynamics of Earth and Jupiter James H. Sheaa) Geology Department, University of Wisconsin—Parkside, Kenosha, Wisconsin 53141 ~Received 3 November 1997; accepted 14 January 1998! 2006-12-09 · See "Ole Rømer, the speed of light, the apparent period of Io, The Doppler effect and the dynamics of Earth and Jupiter" by James H. Shea, American Journal of Physics, 66, July 1998, p. 561-9 Next Stop , In 1676, Ole Roemer didn't really care about the speed of light. He cared about winning a prize to determine the longitude of a ship. The best way to do this was to use a very accurate clock Olaus Roemer became the first person to prove that light travels at a finite speed in 1676.

It was Edmund Halley, in 1694, who found that Rømer’s 22 minutes should instead be 17 minutes; thus Halley gave the speed of light as approximately 300 000 km/s. answers, we can conclude that the speed of light is finite. Rømer did this, at two different times of the year, sometime before 1676, and found no difference in the orbital periods. Therefore, the speed of light is very fast!
