In fact Fresnel had already published his theory that light was a transverse wave but, although Doppler had read Fresnel 's work, he did not accept it. However the error does not really affect the result of Doppler's principle.
Sa katunayan Fresnel ay nai-publish na ang kanyang teorya na ang ilaw ay isang pahalang kaway ngunit, bagama't Doppler had read Fresnel 's trabaho, siya ay hindi tanggapin ito. Subalit ang error ay hindi talagang makakaapekto sa resulta ng Doppler's prinsipyo.
