Velocity factor

The velocity factor (VF) of a transmission medium is the ratio of the speed at which a wavefront (of an electromagnetic signal, a radio signal, a light pulse in an optical fibre or a change of the electrical voltage on a copper wire) passes through the medium, to the speed of light in vacuum. For optical signals, the velocity factor is the reciprocal of the refractive index. The speed of radio waves in vacuum, for example, is the speed of light, and so the velocity factor of a ra
