- In 1676, the Danish astronomer Ole Roemer had one of those “aha” moments in science. He concluded from accumulated observations of eclipses of Jupiter’s moon at different times of the year that light must travel at finite speed and needed 1300 s to cross the diameter of Earth’s orbit around the Sun. Using 300,000,000 1cm for the diameter of Earth’s orbit, calculate the speed of light based on Roemer’s 1300-s estimate. How does it differ from a modern value for the speed of light?6. In what substance in this table is the speed of light 2.203 ✕ 108 m/s?
