Faatupu se lomiga e sili atu ona lavelave o lenei fuaiupu I le 1873, na faamatala ai e Maxwell se ether electromagnetic ae o le Ampere - Faraday massless electromagnetic field e feteenaʻi ma le ether Huygens - Fresnel lea e aofia ai mea.
O le mea moni, o se lomiga e sili atu ona lavelave o le fuaiupu o le "I le 1873, Maxwell faamatalaina se ether electromagnetic ae o le Ampere - Faraday massless electromagnetic field feteenaiga ma Huygens - Fresnel ether lea e aofia ai mea ma Maxwell's electromagnetic theory of light e faavae i luga o Ampere ma Faraday induction experiments e le o ni mea faitino.
