        \n
      • Coupez le fond m\u00e9tallique de la bo\u00eete \u00e0 chips.\u00a0<\/span>\u00a0<\/span><\/li>\n
      • Placez la bo\u00eete \u00e0 jetons sur le carton noir et tracez le plan avec le stylo. D\u00e9coupez trois tranches de ce type.\u00a0<\/span><\/li>\n
      • Prenez une tranche et coupez une fente au centre, coupez trois fentes dans la tranche suivante et cinq fentes dans la troisi\u00e8me tranche. \u00a0<\/span><\/li>\n
      • Prenez le couvercle en plastique transparent et d\u00e9coupez un carr\u00e9 \u00e0 l\u2019aide de ciseaux. \u00a0<\/span><\/li>\n
      • Placez un disque \u00e0 l\u2019extr\u00e9mit\u00e9 du tuyau et fixez-le avec le couvercle en plastique.<\/li>\n
      • Fixez votre t\u00e9l\u00e9phone portable \u00e0 l\u2019autre extr\u00e9mit\u00e9 du tuyau avec du ruban adh\u00e9sif \u00a0<\/span><\/li>\n
      • Allumez la lampe de poche LED \u00a0<\/span><\/li>\n<\/ul>\n

        \u00a0<\/span>Observation:\u00a0<\/span>\u00a0<\/span><\/h2>\n
          \n
        • Des traces de lumi\u00e8re droites peuvent \u00eatre vues sur le plateau de la table.\u00a0<\/span>\u00a0<\/span><\/li>\n<\/ul>\n

          Explication:\u00a0<\/span>\u00a0<\/span><\/h2>\n
            \n
          • La lampe de poche du t\u00e9l\u00e9phone portable \u00e9met un faisceau de lumi\u00e8re en forme de c\u00f4ne. La fente dans l\u2019ouverture ne laisse passer qu\u2019un faisceau de lumi\u00e8re \u00e9troit. Celui-ci tombe l\u00e9g\u00e8rement en diagonale sur la surface et cr\u00e9e une tra\u00een\u00e9e lumineuse, le \u00ab\u202frayon lumineux\u202f\u00bb, gr\u00e2ce \u00e0 une r\u00e9flexion diffuse.\u00a0<\/span>\u00a0<\/span><\/li>\n<\/ul>\n

            Conseils:\u00a0<\/span>\u00a0<\/span><\/h2>\n
              \n
            • Les rayons lumineux sont bons pour exp\u00e9rimenter. Par exemple, ils peuvent \u00eatre r\u00e9fl\u00e9chis par un miroir ou collect\u00e9s ou diffus\u00e9s par des lentilles.\u00a0<\/span><\/li>\n
            • Selon l\u2019exp\u00e9rience, des disques \u00e0 une, deux, trois fentes, etc. conviennent. \u00a0<\/span><\/li>\n
            • Les rayons sont mieux vus dans l\u2019obscurit\u00e9\u00a0<\/span><\/li>\n<\/ul>\n","protected":false},"featured_media":1895,"template":"","meta":[],"product_brand":[],"product_cat":[961,964,967,970,885,895],"product_tag":[],"class_list":{"0":"post-1894","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-1-lumiere-ombre","7":"product_cat-2-reflexion-fr","8":"product_cat-3-refraction-fr","9":"product_cat-4-diffraction-interference-fr","10":"product_cat-c-optique-fr","11":"product_cat-i-appareils-physiques-fr","12":"","13":"woocommerce-text-align-left","14":"woocommerce-image-align-center","16":"first","17":"instock","18":"shipping-taxable","19":"product-type-simple"},"_links":{"self":[{"href":"https:\/\/experiments.school\/fr\/wp-json\/wp\/v2\/product\/1894","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/experiments.school\/fr\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/experiments.school\/fr\/wp-json\/wp\/v2\/types\/product"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/experiments.school\/fr\/wp-json\/wp\/v2\/media\/1895"}],"wp:attachment":[{"href":"https:\/\/experiments.school\/fr\/wp-json\/wp\/v2\/media?parent=1894"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/experiments.school\/fr\/wp-json\/wp\/v2\/product_brand?post=1894"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/experiments.school\/fr\/wp-json\/wp\/v2\/product_cat?post=1894"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/experiments.school\/fr\/wp-json\/wp\/v2\/product_tag?post=1894"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
