what is the equation of speed of light. Using Maxwells equations a relationship can be derived that relates the speed of light to the fundamental constants e 0 and m 0 which are the vacuum permitivity and the permeability of free space. That comes from the derivation that an electromagnetic wave IS light.

Using Maxwells equations a relationship can be derived that relates the speed of light to the fundamental constants e 0 and m 0 which are the vacuum permitivity and the permeability of free space. C 1 me Where m and e are the permeability and permittivity of free space both of which are contants thus c is constant as well. This was realized by Maxwell circa 1864 as soon as the equation c 1e0m012 2998 X 108mswas discovered since the speed of light had been accurately measured by then and its agreement with cwas not likely to be a coincidence. The numerator cycles is not needed and so its presence is simply understood and if writing a fraction is necessary a one would be used as in 1sec.
