WebAug 17, 2016 · The constant speed of light for all reference frames is the fundamental building-block of Relativity. From Maxwell's equations in vacuum one can derive two wave equations ( 1 μ 0 ϵ 0 Δ − ∂ 2 ∂ t 2) E = 0 ( 1 μ 0 ϵ 0 Δ − ∂ 2 ∂ t 2) B = 0, which tells us that the speed of light is equal to 1 μ 0 ϵ 0 . http://www.actforlibraries.org/who-discovered-the-speed-of-light/
