They were predicted by Maxwell, who also showed that c=1√μ0ϵ0, where mu0 is the permeability of free space and ϵ0 is the permitivity of free space. Maxwell’s prediction of electromagnetic waves resulted from his formulation of a complete and symmetric theory of electricity and magnetism, known as Maxwell’s equations.
