Cut out three such slices.<\/li>\n<li>Take a slice and cut a slit to the center, cut three slits in the next slice and five slits in the third slice.<\/li>\n<li>Take the clear plastic lid and cut out a square with the help of scissors.<\/li>\n<li>Place a disc on the end of the pipe and secure it with the plastic lid.<\/li>\n<li>Attach your mobile phone to the other end of the pipe with tape<\/li>\n<li>Turn on the LED flashlight<\/li>\n<\/ul>\n<h2>Observation:<\/h2>\n<ul>\n<li>Straight traces of light can be seen on the tabletop.<\/li>\n<\/ul>\n<h2>Explication:<\/h2>\n<ul>\n<li>The mobile phone flashlight emits a cone-shaped beam of light. The slit in the aperture only allows a narrow beam of light to pass through. This falls slightly diagonally on the surface and creates a light trail, the &#8220;light ray&#8221;, through diffuse reflection.<\/li>\n<\/ul>\n<h2>Tips:<\/h2>\n<ul>\n<li>The light rays are good for experimenting. For example, they can be reflected by a mirror or collected or scattered by lenses.<\/li>\n<li>Depending on the experiment, discs with one, two, three slits, etc. are suitable.<\/li>\n<li>The rays are best seen in the dark<\/li>\n<\/ul>\n","protected":false},"featured_media":1893,"template":"","meta":[],"product_brand":[],"product_cat":[960,963,966,969,875,881],"product_tag":[],"class_list":{"0":"post-1892","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-1-light-shadow","7":"product_cat-2-reflection","8":"product_cat-3-refraction","9":"product_cat-4-diffraction-interference","10":"product_cat-c-optics","11":"product_cat-i-physical-devices","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\/en\/wp-json\/wp\/v2\/product\/1892","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\/1893"}],"wp:attachment":[{"href":"https:\/\/experiments.school\/en\/wp-json\/wp\/v2\/media?parent=1892"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/experiments.school\/en\/wp-json\/wp\/v2\/product_brand?post=1892"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/experiments.school\/en\/wp-json\/wp\/v2\/product_cat?post=1892"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/experiments.school\/en\/wp-json\/wp\/v2\/product_tag?post=1892"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
