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. His method was based on observations of the eclipses of the moons of Jupiter.

2021-02-27 · While his 17th-century contemporaries were debating the nature of light, Ole Rømer was busy measuring its velocity. This little-known Danish scientist was the first to determine that light moves at a finite speed.

The average computed over the long time period will exhibit cumulative effect of the speed of light by being noticeably longer or shorter than the average computed over the short time period. More observations will help you make a more accurate determination of the speed of light. The speed of light was then estimated to account for the seven minute overall variation of the observed interval between successive eclipses.

Frances Willmoth Römer, Flamsteed, Cassini and the Speed of Light, Centaurus 54, 2017-05-02 They both attributed such discrepancies to the finite speed of light and Cassini publicized his findings in the Academy of Sciences on 22 August 1676: This second inequality appears to be due to light taking some time to reach us from the satellite; light seems to take about ten to eleven minutes [to cross] a distance equal to the half-diameter of the terrestrial orbit Earth approaching 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 Roemer needed to use those planets because the speed of light is just too quick to do it with anything smaller – something that Gallileo found when he tried to measure its speed by sending light 2021-02-27 Ole Rømer's (1676) method of using variations in the apparent period of Jupiter's moon, Io, to demonstrate that the speed of light is finite made use of what we would today call a ``Doppler'' method. He did this 166 years before Christian Doppler described what we now call the Doppler effect and the mechanism in 1842. Although the method Rømer conceived is unquestionably valid, his original Romer estimated that the speed of light was 214000 km/s.
