    Material:\u00a0<\/span>\u00a0<\/span><\/h2>\n
      \n
    • CD (Compact Disc)\u00a0<\/span>\u00a0<\/span><\/li>\n
    • Flashlight\u00a0<\/span>\u00a0<\/span><\/li>\n
    • Shade to catch the light (e.g. white wall)\u00a0<\/span>\u00a0<\/span><\/li>\n<\/ul>\n

      Instructions:<\/span>\u00a0<\/span><\/h2>\n
        \n
      • Light at an angle of about 45\u00b0 on the CD\u00a0<\/span>\u00a0<\/span><\/li>\n
      • Hold the CD so that the reflected light falls on the screen\u00a0<\/span>\u00a0<\/span><\/li>\n<\/ul>\n

        Observation:\u00a0<\/span>\u00a0<\/span><\/h2>\n
          \n
        • In addition to a very bright, white luminous dot, you can see a colorful color spectrum.\u00a0\u00a0<\/span>\u00a0<\/span><\/li>\n
        • In addition, there may be a second spectrum that is much weaker.\u00a0<\/span>\u00a0<\/span><\/li>\n<\/ul>\n

          Explication:<\/span>\u00a0<\/span><\/h2>\n
            \n
          • The grooves of the CD act as a gitter through which the light rays of the flashlight pass.\u00a0<\/span>\u00a0<\/span><\/li>\n
          • The bright point of light is the main maximum of the interference figure, the colorful spectrum results from the first minor maxima. <\/span>Depending on the frequency of the light, the first secondary maximum is at a different location.\u00a0<\/span>\u00a0<\/span><\/li>\n
          • It is possible that the spectrum of the second minor maxima can still be seen.\u00a0<\/span>\u00a0<\/span><\/li>\n<\/ul>\n

            Tips:\u00a0<\/span>\u00a0<\/span><\/h2>\n
              \n
            • The gitter spacing of the grooves of the CD is 1.6 \u03bcm. This information can also be used to carry out quantitative measurements or calculations.\u00a0<\/span>\u00a0<\/span><\/li>\n<\/ul>\n","protected":false},"featured_media":1799,"template":"","meta":[],"product_brand":[],"product_cat":[969,875],"product_tag":[],"class_list":{"0":"post-1797","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-4-diffraction-interference","7":"product_cat-c-optics","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\/en\/wp-json\/wp\/v2\/product\/1797","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/experiments.school\/en\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/experiments.school\/en\/wp-json\/wp\/v2\/types\/product"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/experiments.school\/en\/wp-json\/wp\/v2\/media\/1799"}],"wp:attachment":[{"href":"https:\/\/experiments.school\/en\/wp-json\/wp\/v2\/media?parent=1797"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/experiments.school\/en\/wp-json\/wp\/v2\/product_brand?post=1797"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/experiments.school\/en\/wp-json\/wp\/v2\/product_cat?post=1797"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/experiments.school\/en\/wp-json\/wp\/v2\/product_tag?post=1797"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
