The speed of EM wave happened to coincide with the experimentally measured value of the speed of light.
In an 1864 lecture before the Royal Society of London A Dynamical Theory of the Electro-Magnetic Field Maxwell asserted. James Clerk Maxwell derived a wave form of the electric and magnetic equations thus uncovering the wave-like nature of electric and magnetic fields and their symmetryBecause the speed of EM waves predicted by the wave equation coincided with the measured speed of light Maxwell concluded that light itself is an EM wave. P u For a plane electromagnetic wave. Electromagnetic waves can have any wavelength l or frequency f as long as lf c.
