La fr\u00e9quence d’une onde est identique lorsque l’onde passe d’un milieu \u00e0 un autre avec une vitesse diff\u00e9rente. Mais sa longueur d’onde peut varier.<\/span><\/p>\n\n <\/div>\n <\/section>\n\n\n\nLa longueur d’onde est li\u00e9e \u00e0 la taille des motifs r\u00e9p\u00e9titifs d’une onde<\/strong>. Dans le cas de la lumi\u00e8re, la longueur d’onde correspond \u00e0 la distance entre deux cr\u00eates<\/strong> ou deux creux d’une onde \u00e9lectromagn\u00e9tique.<\/p>\n\n\n\n Une cr\u00eate, c’est quoi ? \ud83e\uddd0<\/span><\/p>\n<\/div>\n \n
\u00a0Une cr\u00eate est la partie haute d’une onde<\/strong> alors qu’un creux est la partie basse.<\/span><\/p>\n\n <\/div>\n <\/section>\n\n\n\nLa longueur d’onde est un concept essentiel pour comprendre et caract\u00e9riser les ondes, que ce soit dans le domaine de la physique ou encore de l’astronomie<\/strong>. Elle permet de d\u00e9crire la mani\u00e8re dont elles se propagent \u00e0 travers l’espace et influencent notre perception des ph\u00e9nom\u00e8nes ondulatoires.<\/p>\n\n\n\n
