Romers calculation of speed of light

WebAccording to Rømer’s observations, light traverses this distance in 22 minutes. To keep things simple, Huygens rounded the speed down to 1000 diameters per minute, or 212 400 km/s. Without the rounding, his speed of light would have been 232 000 km/s. It was Edmund Halley, in 1694, who found that Rømer’s 22 minutes should instead be 17 ... WebOct 7, 2014 · Cassini argued that Rømer’s equation did not apply to the eclipses of Jupiter’s other moons, therefore it could not represent the speed of light. Other members were …
