Rømer's determination of the speed of light was the demonstration in 1676 that light has an apprehensible, measurable speed and so does not travel instantaneously. The discovery is usually attributed to Danish astronomer Ole Rømer , [note 1] who was working at the Royal Observatory in Paris at the time.
In 1676, the Danish astronomer Ole Roemer (1644–1710) became the first person to measure the speed of light. Roemer measured the speed of light by timing eclipses of Jupiter's moon Io. In this figure, S is the Sun, E1 is the Earth when closest to Jupiter (J1) and E2 is the Earth about six months later, on the opposite side of the Sun from ...
Al cronometrar los eclipses de la luna Júpiter Io, Rømer estimó que la luz tardaría unos 22 minutos en recorrer una distancia igual al diámetro de la órbita de la Tierra alrededor del Sol. Esto daría a la luz una velocidad de unos 220 000 kilómetros por segundo, aproximadamente un 26% menos que el valor real de la 299 792 km/s .
Rømer measured the speed of light to be approximately 220,000 kilometers per second while working at the Royal Observatory in Paris. Rømer made this approximation while he was conducting studies of Jupiter's moon Io. As of the 21st century, the speed of light has been measured to be just under 300,000 kilometers per second.
7 de oct. de 2014 · The speed of light is a quantity that eluded some of the most renowned scholars in history, including Augustine and Galileo. In fact, at the time of Rømer’s successful prediction, there was ongoing debate over whether light had a measurable speed at all, or was somehow transmitted instantaneously.
Ole Christensen Rømer ( Århus, 25 de septiembre de 1644- Copenhague, 19 de septiembre de 1710) 1 fue un astrónomo danés, famoso por ser la primera persona en determinar la velocidad de la luz en el año 1676 con un valor inicial de 225.000 km/s.
1 de dic. de 2004 · Ole Rømer’s 1676 demonstration that light propagates at a finite speed must have been a revelation to the members of the French Royal Academy of Science. A young and brilliant Danish “postdoc” at the Paris Observatory, Rømer had unexpectedly answered a long-standing fundamental question.
