    • Miroir\u00a0\u00a0<\/span>\u00a0<\/span><\/li>\n
    • Lampe de poche \/ Source de lumi\u00e8re\u00a0<\/span>\u00a0<\/span><\/li>\n
    • Fond noir \/ Papier \/ Tissu\u00a0<\/span>\u00a0<\/span><\/li>\n<\/ul>\n

      Ex\u00e9cution:\u00a0<\/span>\u00a0<\/span><\/h2>\n
        \n
      • Placez le miroir devant le fond noir.\u00a0<\/span>\u00a0<\/span><\/li>\n
      • Regardez le miroir de mani\u00e8re \u00e0 ne voir que du noir.\u00a0<\/span>\u00a0<\/span><\/li>\n
      • Faites briller la lampe de poche sur le miroir de c\u00f4t\u00e9, perpendiculairement \u00e0 la direction de votre regard, sans \u00e9clairer le fond noir.<\/span>\u00a0<\/span><\/li>\n<\/ul>\n

        Observation:\u00a0<\/span>\u00a0<\/span><\/h2>\n
          \n
        • L\u2019arri\u00e8re-plan autour du miroir est fortement \u00e9clair\u00e9, tandis que le miroir reste noir.\u00a0<\/span>\u00a0<\/span><\/li>\n<\/ul>\n

          Conseil:<\/span>\u00a0<\/span><\/h2>\n
            \n
          • L\u2019effet est particuli\u00e8rement bon lorsque l\u2019arri\u00e8re-plan est blanc et que la pi\u00e8ce est l\u00e9g\u00e8rement assombrie.\u00a0<\/span>\u00a0<\/span><\/li>\n<\/ul>\n

            Explication:\u00a0<\/span>\u00a0<\/span><\/h2>\n
              \n
            • La lumi\u00e8re qui tombe sur le miroir est r\u00e9fl\u00e9chie dans une direction o\u00f9 l\u2019\u0153il de l\u2019observateur ne l\u2019est pas. Si l\u2019arri\u00e8re-plan est noir, le miroir appara\u00eetra \u00e9galement noir. L\u2019environnement du miroir, quant \u00e0 lui, r\u00e9fl\u00e9chit la lumi\u00e8re de mani\u00e8re diffuse, c\u2019est-\u00e0-dire qu\u2019il la diffuse dans toutes les directions, y compris celle de l\u2019\u0153il de l\u2019observateur. C\u2019est pourquoi les environs semblaient brillamment \u00e9clair\u00e9s.<\/span>\u00a0<\/span><\/li>\n<\/ul>\n","protected":false},"featured_media":1849,"template":"","meta":[],"product_brand":[],"product_cat":[964,885],"product_tag":[],"class_list":{"0":"post-1847","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\/1847","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\/1849"}],"wp:attachment":[{"href":"https:\/\/experiments.school\/fr\/wp-json\/wp\/v2\/media?parent=1847"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/experiments.school\/fr\/wp-json\/wp\/v2\/product_brand?post=1847"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/experiments.school\/fr\/wp-json\/wp\/v2\/product_cat?post=1847"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/experiments.school\/fr\/wp-json\/wp\/v2\/product_tag?post=1847"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
