The speed of light in vacuum, commonly denoted c, is a universal physical constant that is exactly equal to 299,792,458 metres per second (approximately 300,000 kilometres per second; 186,000 miles per second; 671 million miles per hour). According to the special theory of relativity, c is the upper limit for … See more The speed of light in vacuum is usually denoted by a lowercase c, for "constant" or the Latin celeritas (meaning 'swiftness, celerity'). In 1856, Wilhelm Eduard Weber and Rudolf Kohlrausch had used c for a different constant … See more In classical physics, light is described as a type of electromagnetic wave. The classical behaviour of the electromagnetic field is described by Maxwell's equations, which predict that … See more There are different ways to determine the value of c. One way is to measure the actual speed at which light waves propagate, which … See more The speed at which light waves propagate in vacuum is independent both of the motion of the wave source and of the inertial frame of reference See more There are situations in which it may seem that matter, energy, or information-carrying signal travels at speeds greater than c, but they do not. For … See more The speed of light is of relevance to communications: the one-way and round-trip delay time are greater than zero. This applies from small to astronomical scales. On the other hand, some techniques depend on the finite speed of light, for example in distance … See more Until the early modern period, it was not known whether light travelled instantaneously or at a very fast finite speed. The first … See more WebJul 16, 2024 · We all know and love the speed of light — 299,792,458 meters per second — but why does it have the value that it does? Why isn't it some other number?
