<prompt> Yakha inguqulo eyinkimbinkimbi yalesi sigwebo Ngo-1873, uMaxwell uchaza i-ether kagesi kodwa i-ampere - Faraday massless electromagnetic field ingqubuzana ne-Huygens - Fresnel ether eyakhiwe ngendaba.  <response>: Yiqiniso, inguqulo eyinkimbinkimbi yomusho ithi Ngo - 1873, uMaxwell uchaza i - ether kagesi kodwa i - Ampere - Faraday massless electromagnetic field ingqubuzana ne - Huygens - Fresnel ether eyakhiwe ngento futhi i - Maxwells electromagnetic theory of light isekelwe ku - Ampere no - Faraday induction experiments okungewona ama - optical.
