Sunlight is first refracted (bent) as it enters the water droplet. It is then internally reflected off the back inner surface of the droplet. Finally, it is refracted again as it exits the droplet. The different wavelengths (colors) of light are refracted at slightly different angles (dispersion), separating the white light into the spectrum of colors observed in a rainbow.<\/section>\n<section id=\"pyq-additional-information\">A primary rainbow involves one internal reflection and results in the colors ordered from red on the outside to violet on the inside. A secondary rainbow involves two internal reflections, reversing the color order (violet on the outside, red on the inside), and is typically fainter than the primary rainbow.<\/section>\n","protected":false},"excerpt":{"rendered":"<p>The phenomenon of rainbow formation by water droplets involves : [amp_mcq option1=&#8221;single refraction of sunlight&#8221; option2=&#8221;one internal reflection of sunlight&#8221; option3=&#8221;two internal reflections of sunlight&#8221; option4=&#8221;both refraction and internal reflection of sunlight&#8221; correct=&#8221;option4&#8243;] This question was previously asked in UPSC CDS-2 &#8211; 2024 Download PDFAttempt Online The phenomenon of rainbow formation by water droplets involves &#8230; <\/p>\n<p class=\"read-more-container\"><a title=\"The phenomenon of rainbow formation by water droplets involves :\" class=\"read-more button\" href=\"https:\/\/exam.pscnotes.com\/mcq\/the-phenomenon-of-rainbow-formation-by-water-droplets-involves\/#more-86539\">Detailed Solution<span class=\"screen-reader-text\">The phenomenon of rainbow formation by water droplets involves :<\/span><\/a><\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1088],"tags":[1103,1153,1128],"class_list":["post-86539","post","type-post","status-publish","format-standard","hentry","category-upsc-cds-2","tag-1103","tag-optics","tag-physics","no-featured-image-padding"],"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v22.2 (Yoast SEO v23.3) - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>The phenomenon of rainbow formation by water droplets involves :<\/title>\n<meta name=\"description\" content=\"The phenomenon of rainbow formation by water droplets involves both refraction and internal reflection of sunlight.
