In 1598 Philip III of Spain had offered a prize for a method to determine the longitude of a ship out of sight of land. Galileo proposed a method of establishing the time of day, and thus longitude, based on the times of the eclipses of the moons of Jupiter, in essence using the Jovian system as a cosmic clock; this method was not significantl…

How did Galileo determine the speed of light?

WebThe problem was that the speed of light is simply too fast to be measured this way; light takes such a short time (about 0.000005 seconds, in fact) to travel one mile that there's no way the interval could have been measured using the tools Galileo had. ... (The idea behind this experiment is not so different from Galileo's, if you think about ... WebHow did Maxwell calculate the speed of light? c = 1/ (em)1/2 = 2.998 X 108m/s. Light is an electromagnetic wave: this was realized by Maxwell circa 1864, as soon as the equation c = 1/ (em)1/2 = 2.998 X 108m/s was discovered, since the speed of light had been accurately measured by then, and its agreement with c was not likely to be a coincidence.
