== Définition ==&lt;br /&gt;
L’indice de réfraction est une propriété déterminante des matériaux permettant de quantifier le ralentissement de la lumière lorsqu’elle traverse un matériau diélectrique par rapport à la vitesse de phase de la lumière dans le vide (ou l’espace libre). Son symbole est la lettre « n ». Dans l’espace (vide), l’indice de réfraction est de 1. &lt;br /&gt;
&lt;br /&gt;
Si la fréquence d’une onde optique ne change pas dans un milieu, sa longueur d’onde est diminuée par le n (λ⁄n). Le changement d’indice de réfraction entraîne une perte de puissance et la modification du trajet de la lumière lorsqu’elle pénètre dans un nouveau milieu (par exemple, la lumière passant de l’air à l’eau).&lt;br /&gt;
