White Light Becomes a Seven-Color Puzzle \u2014 The World of Light Loved by Newton"},"content":{"rendered":"<p style=\"text-align: center;\"><strong style=\"color: #339966;\">Hi, I\u2019m Ken Kuwako, your Science Trainer. To me, every day is an experiment!<\/strong><\/p>\n<p>Have you ever gazed at a rainbow shimmering in the sky after a storm, or marveled at the swirling colors on the surface of a soap bubble? We\u2019ve all wondered at some point: &#8220;Where do all these colors come from?&#8221;<\/p>\n<p>As it turns out, the ordinary &#8220;white light&#8221; all around us is actually hiding a spectacular parade of colors. Today, I\u2019ll show you how to reveal this hidden beauty using a magical scientific tool: the prism.<\/p>\n<h3>Unmasking Light: The Magic of Prisms<\/h3>\n<p>We\u2019re often taught that light travels in a straight line. While that\u2019s generally true, light can actually change its path dramatically under the right conditions. This fascinating phenomenon is called dispersion.<\/p>\n<p>First, take a look at this video to see how light transforms right before your eyes!<\/p>\n<p><iframe loading=\"lazy\" title=\"\u30d7\u30ea\u30ba\u30e0\u306b\u5f53\u3066\u305f\u6642\u306e\u5149\u306e\u5206\u6563\u306e\u69d8\u5b50\uff08\u767d\u8272\u3001\u8d64\u8272\u3001\u7dd1\u8272\u30d0\u30fc\u30b8\u30e7\u30f3\uff09\" width=\"1140\" height=\"641\" src=\"https:\/\/www.youtube.com\/embed\/B5TtJKYQa6M?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe><\/p>\n<p>When you shine white light through a prism, it emerges on the other side as a stunning rainbow. This happens because white light is actually a blend of many different wavelengths. Each color (or wavelength) has a slightly different refractive index, meaning they bend at different angles as they pass through the glass. That tiny difference in the bend results in a beautiful spread of colors at the exit.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-43754 aligncenter\" src=\"https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2023\/10\/099e8ff19cebd2347125214d3b3f883f-scaled.jpg\" alt=\"\" width=\"697\" height=\"523\" srcset=\"https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2023\/10\/099e8ff19cebd2347125214d3b3f883f-scaled.jpg 2560w, https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2023\/10\/099e8ff19cebd2347125214d3b3f883f-300x225.jpg 300w, https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2023\/10\/099e8ff19cebd2347125214d3b3f883f-1024x768.jpg 1024w, https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2023\/10\/099e8ff19cebd2347125214d3b3f883f-768x576.jpg 768w, https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2023\/10\/099e8ff19cebd2347125214d3b3f883f-1536x1152.jpg 1536w, https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2023\/10\/099e8ff19cebd2347125214d3b3f883f-2048x1536.jpg 2048w\" sizes=\"auto, (max-width: 697px) 100vw, 697px\" \/><\/p>\n<h3>Monochromatic Light: Seeing the Bend<\/h3>\n<p>Now, what happens if we use a red or green laser instead? Since these are &#8220;monochromatic&#8221; (single-color) lights, they only have one wavelength. This means they won\u2019t split into a rainbow; they just pass through as a single beam.<\/p>\n<p>However, the real secret is in the angle of the bend. If you compare the images closely, you\u2019ll notice that the green light bends more sharply than the red light.<\/p>\n<p>This is because green light has a shorter wavelength than red light, causing it to be more affected\u2014and thus refracted more\u2014by materials like glass. This specific difference in how colors bend is the fundamental &#8220;recipe&#8221; for creating a rainbow.<\/p>\n<h3>Tips for a Successful Experiment<\/h3>\n<p>Whether you\u2019re trying this in a classroom or at home, here are a few tips to make the experience even more impactful:<\/p>\n<h3>What You\u2019ll Need<\/h3>\n<p>\u30fbTriangular Prism (Acrylic or glass works fine, but high transparency is best!) \u30fbLight Sources (A white LED flashlight, plus red and green laser pointers) \u30fbBlack Construction Paper or a Screen (To make the light beams pop) \u30fbA Dark Room (Just closing the curtains makes the path of light much easier to see)<\/p>\n<h3>Step-by-Step Guide<\/h3>\n<p>Darken the room, aim your white light at the edge of the prism, and project it onto your screen.<\/p>\n<p>Observe the process of spectral decomposition\u2014how the light fans out into a rainbow.<\/p>\n<p>Switch to the red laser and mark where the light hits the screen.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-43753 aligncenter\" src=\"https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2023\/10\/ffc5c50268fff145cef390d34177ef1e-scaled.jpg\" alt=\"\" width=\"773\" height=\"580\" srcset=\"https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2023\/10\/ffc5c50268fff145cef390d34177ef1e-scaled.jpg 2560w, https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2023\/10\/ffc5c50268fff145cef390d34177ef1e-300x225.jpg 300w, https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2023\/10\/ffc5c50268fff145cef390d34177ef1e-1024x768.jpg 1024w, https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2023\/10\/ffc5c50268fff145cef390d34177ef1e-768x576.jpg 768w, https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2023\/10\/ffc5c50268fff145cef390d34177ef1e-1536x1152.jpg 1536w, https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2023\/10\/ffc5c50268fff145cef390d34177ef1e-2048x1536.jpg 2048w\" sizes=\"auto, (max-width: 773px) 100vw, 773px\" \/><\/p>\n<p>Switch to the green laser.
