Dans un cristal anisotrope, il existe à chaque fréquence [de la lumière incidente], deux valeurs de l'indice de réfraction: l'indice "ordinaire" et l'indice "extraordinaire". Le premier (...) ne dépend pas de la direction de propagation; par contre, l'indice extraordinaire varie entre deux valeurs extrêmes (...) en fonction de l'angle que forment la direction de propagation de la lumière et l'axe optique du cristal. 2, record 2, French, - indice%20extraordinaire

indice de réfraction: rapport constant entre le sinus de l'angle d'incidence et le sinus de l'angle de réfraction, dans un même milieu. 3, record 2, French, - indice%20extraordinaire
