The speed of light is more of a hot topic than ever nowadays. Light moves at the speed of 299 792 458 meters per second, what approximately gives 300 000 kilometers per hour or 186 000 miles per second. Speed of light, speed at which light waves propagate through different materials. The first real measurement of the speed of light came about half a century later, in 1676, by a Danish astronomer, Ole Römer, working at the Paris Observatory.He had made a systematic study of Io, one of the moons of Jupiter, which was eclipsed by Jupiter at regular intervals, as Io went around Jupiter in a circular orbit at a steady rate. We assume you are converting between speed of light [air] and mile/hour. atm.)
