WebFeb 3, 2009 · speed of light, speed at which light waves propagate through different materials. In particular, the value for the speed of light in a vacuum is now defined as exactly 299,792,458 metres per second. The speed of light is considered a fundamental constant … E = mc2, equation in German-born physicist Albert Einstein’s theory of special rela… WebSymbol: c . The constant speed at which light and other electromagnetic radiation travels in a vacuum. It is equal to 299 792 458 m s –1 (value adopted by the IAU in 1976). Since space is not a perfect vacuum, radiation travels through space at a very slightly lower speed, which decreases somewhat when the radiation enters the Earth's atmosphere.
