The key insight to gain from this derivation is that electromagnetic waves (light) always travel at one and the same speed in vacuum. Web15 mrt. 2024 · This, as a side note, is why the speed of light is labeled “c” in Einstein’s famous E=mc2 equation. Maxwell’s Theory on Electromagnetic Waves Anyway, in 1865, Maxwell wrote a paper on electromagnetic forces where he coined the term “fields” as compared to Faraday’s “lines of force”.
