By timing the eclipses of Jupiter's 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. Using modern orbits, this would imply a speed of light of 226,663 kilometres per second, 24.4% lower than the true value of 299,792 km/s.
La determinación de Rømer de la velocidad de la luz fue la demostración, en 1676, de que la velocidad de la luz tiene una velocidad finita y, por tanto, no se desplaza instantáneamente. El descubrimiento se suele atribuir al astrónomo danés (1644-1710), nota 1 que trabajaba en el Observatorio Real en París en ese momento.
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 ...
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.
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.
Rømer made his discovery regarding the speed of light while working at the Royal Observatory in Paris and studying Jupiter's moon Io. He estimated that light takes about 11 minutes to travel from the Sun to Earth.
7 de oct. de 2014 · Ole Rømer and the Speed of Light In 1676, Danish astronomer Ole Rømer predicted that an eclipse of one of Jupiter’s moons would occur ten minutes later than expected. How did he know?
