WebbThe 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.

WebbIn a nutshell: The color we percieve an object to have, is the light that was reflected by that object. For example, a (yellow) banana is reflecting light of approximately 580 nm wavelength. It absorbs the rest (or at least the rest of the visible wavelengths). So the color we see is the light that is reflected.

WebbA Short Answer. Although c is now the universal symbol for the speed of light, the most common symbol in the nineteenth century was an upper-case V which Maxwell had started using in 1865. That was the notation adopted by Einstein for his first few papers on relativity from 1905. The origins of the letter c being used for the speed of light can ...
