Publisher's Synopsis
Excerpt from Trait� d'Optique, Vol. 3
Par la m�me raison, la lumi�re naturelle, qui �quivaut � deux faisceaux d'�gale intensit� polaris�s � angle droit, doit fournir par diffraction de la lumi�re partiellement polaris�e. Cette question importante est l'objet principal du M�moire de Sir G. Stokes sur la th�orie dynamique de la diffraction. Pour expliquer la propagation des vibrations transversales, il est n�cessaire de supposer qu'il existe, sur chaque �l�ment du milieu �branl�, une composante tangentielle de la pression; cette force est mise enjeu par le glissement des couches voisines et proportion nelle � leur d�placement relatif.
