In 1856, Wilhelm Eduard Weber and Rudolf Kohlrausch had used c for a different … Meer weergeven 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 the speed c with which electromagnetic waves (such as light) propagate in … Meer weergeven There are different ways to determine the value of c. One way is to measure the actual speed at which light waves propagate, … Meer weergeven Until the early modern period, it was not known whether light travelled instantaneously or at a very fast finite speed. The … Meer weergeven 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 of the observer. This … Meer weergeven 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 example, as is discussed in the propagation of light in a medium section below, many wave velocities can exceed c. The Meer weergeven 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.
