    • Note de s\u00e9curit\u00e9 : Risque d\u2019endommagement de la r\u00e9tine, utilisez donc des LASERS \u00e0 faible puissance de rayonnement. Ne travaillez jamais sans lunettes de s\u00e9curit\u00e9 LASER !)\u00a0<\/span>\u00a0<\/span><\/li>\n
    • Miroir\u00a0<\/span>\u00a0<\/span><\/li>\n
    • 2 feuilles de papier blanc (A5)\u00a0<\/span>\u00a0<\/span><\/li>\n
    • Colle \/ Ruban adh\u00e9sif\u00a0<\/span>\u00a0<\/span><\/li>\n<\/ul>\n

      Instructions:<\/span>\u00a0<\/span><\/h2>\n
        \n
      • Collez une feuille de papier ensemble pour former un tube cylindrique.\u00a0<\/span>\u00a0<\/span><\/li>\n
      • Tout d\u2019abord, placez le tube sur le miroir et faites briller le pointeur laser \u00e0 travers le tube aussi verticalement que possible sur le miroir. Assurez-vous que le faisceau r\u00e9fl\u00e9chi ne frappe pas le tube !\u00a0<\/span>\u00a0<\/span><\/li>\n
      • Placez maintenant le tube sur la deuxi\u00e8me feuille de papier et faites briller \u00e0 nouveau le pointeur laser presque verticalement sur le papier.<\/span>\u00a0<\/span><\/li>\n<\/ul>\n

        Observation:\u00a0<\/span>\u00a0<\/span><\/h2>\n
          \n
        • Lors de la premi\u00e8re tentative, le cylindre reste sombre, vous pouvez voir le faisceau r\u00e9fl\u00e9chi soit sur la main, soit sur le plafond.\u00a0<\/span>\u00a0<\/span><\/li>\n
        • Lors de la deuxi\u00e8me tentative, l\u2019ensemble du cylindre brille de la couleur du pointeur laser.\u00a0<\/span>\u00a0<\/span><\/li>\n<\/ul>\n

          Explication:\u00a0<\/span>\u00a0<\/span><\/h2>\n
            \n
          • Alors que le faisceau lumineux sur le miroir n\u2019est r\u00e9fl\u00e9chi que dans une seule direction, le faisceau est diffus\u00e9 dans toutes les directions sur la surface rugueuse du papier. Ces faisceaux \u00e9clairent le cylindre de papier de l\u2019int\u00e9rieur.<\/span>\u00a0<\/span><\/li>\n<\/ul>\n","protected":false},"featured_media":1860,"template":"","meta":[],"product_brand":[],"product_cat":[964,885],"product_tag":[],"class_list":{"0":"post-1859","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-2-reflexion-fr","7":"product_cat-c-optique-fr","8":"","9":"woocommerce-text-align-left","10":"woocommerce-image-align-center","12":"first","13":"instock","14":"shipping-taxable","15":"product-type-simple"},"_links":{"self":[{"href":"https:\/\/experiments.school\/fr\/wp-json\/wp\/v2\/product\/1859","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\/1860"}],"wp:attachment":[{"href":"https:\/\/experiments.school\/fr\/wp-json\/wp\/v2\/media?parent=1859"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/experiments.school\/fr\/wp-json\/wp\/v2\/product_brand?post=1859"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/experiments.school\/fr\/wp-json\/wp\/v2\/product_cat?post=1859"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/experiments.school\/fr\/wp-json\/wp\/v2\/product_tag?post=1859"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
