QUE SIGNIFIE REFRACTING EN ANGLAIS
Réfraction
La réfraction est le changement de direction d'une onde due à une modification de son moyen de transmission. La réfraction est essentiellement un phénomène de surface. Le phénomène concerne principalement la gouvernance de la loi de conservation de l'énergie et de l'élan. En raison du changement de milieu, la vitesse de phase de l'onde est modifiée mais sa fréquence reste constante. Ceci est le plus souvent observé lorsqu'une onde passe d'un moyen à l'autre à n'importe quel angle autre que 90 ° ou 0 °. La réfraction de la lumière est le phénomène le plus fréquent, mais tout type de vague peut se réfracter lorsqu'elle interagit avec un médium, par exemple lorsque les ondes sonores passent d'un milieu à l'autre ou lorsque les ondes d'eau se déplacent dans l'eau d'une profondeur différente. La réfraction est décrite par la loi de Snell, qui indique que, pour une paire donnée de média et une onde avec une fréquence unique, le rapport des sinus de l'angle d'incidence θ1 et l'angle de réfraction θ2 est équivalent au rapport des vitesses de phase dans Deux médias, ou ...
