The primary rainbow is at an angle of 42<sup>\u25e6 <\/sup>while the secondary rainbow at an angle of 51<sup>\u25e6 <\/sup>\u00a0together forming concentric semicircles. The two arches are due to double refraction of light from the sun through circular rain drops. A rainbow is actually a full circle, being on land one can only see the hemispherical arch as the remaining semicircle is blocked by the ground and horizon. If I could see this same rainbow from the pilot\u2019s seat of an airborne plane, I would see it as a perfect circle!<\/p>\n<p>Dhruv Reddi<\/p>\n<p>S5ENA \u2013 European School Karlsruhe<\/p>\n<p>14<sup>th<\/sup> February 2022<\/p>\n\n\t\t<style type=\"text\/css\">\n\t\t\t#gallery-1 {\n\t\t\t\tmargin: auto;\n\t\t\t}\n\t\t\t#gallery-1 .gallery-item {\n\t\t\t\tfloat: left;\n\t\t\t\tmargin-top: 10px;\n\t\t\t\ttext-align: center;\n\t\t\t\twidth: 33%;\n\t\t\t}\n\t\t\t#gallery-1 img {\n\t\t\t\tborder: 2px solid #cfcfcf;\n\t\t\t}\n\t\t\t#gallery-1 .gallery-caption {\n\t\t\t\tmargin-left: 0;\n\t\t\t}\n\t\t\t\/* see gallery_shortcode() in wp-includes\/media.php *\/\n\t\t<\/style>\n\t\t<div id='gallery-1' class='gallery galleryid-113937 gallery-columns-3 gallery-size-medium'><dl class='gallery-item'>\n\t\t\t<dt class='gallery-icon landscape'>\n\t\t\t\t<a href='https:\/\/www.es-karlsruhe.eu\/wp-content\/uploads\/2022\/06\/Dhruv_Photomath_2-scaled.jpg'><img loading=\"lazy\" decoding=\"async\" width=\"300\" height=\"118\" src=\"https:\/\/www.es-karlsruhe.eu\/wp-content\/uploads\/2022\/06\/Dhruv_Photomath_2-300x118.jpg\" class=\"attachment-medium size-medium\" alt=\"\" srcset=\"https:\/\/www.es-karlsruhe.eu\/wp-content\/uploads\/2022\/06\/Dhruv_Photomath_2-300x118.jpg 300w, https:\/\/www.es-karlsruhe.eu\/wp-content\/uploads\/2022\/06\/Dhruv_Photomath_2-1024x403.jpg 1024w, https:\/\/www.es-karlsruhe.eu\/wp-content\/uploads\/2022\/06\/Dhruv_Photomath_2-768x302.jpg 768w, https:\/\/www.es-karlsruhe.eu\/wp-content\/uploads\/2022\/06\/Dhruv_Photomath_2-1536x604.jpg 1536w, https:\/\/www.es-karlsruhe.eu\/wp-content\/uploads\/2022\/06\/Dhruv_Photomath_2-2048x805.jpg 2048w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><\/a>\n\t\t\t<\/dt><\/dl><dl class='gallery-item'>\n\t\t\t<dt class='gallery-icon landscape'>\n\t\t\t\t<a href='https:\/\/www.es-karlsruhe.eu\/wp-content\/uploads\/2022\/06\/Photomath_2022_Dhruv.jpg'><img loading=\"lazy\" decoding=\"async\" width=\"300\" height=\"203\" src=\"https:\/\/www.es-karlsruhe.eu\/wp-content\/uploads\/2022\/06\/Photomath_2022_Dhruv-300x203.jpg\" class=\"attachment-medium size-medium\" alt=\"\" srcset=\"https:\/\/www.es-karlsruhe.eu\/wp-content\/uploads\/2022\/06\/Photomath_2022_Dhruv-300x203.jpg 300w, https:\/\/www.es-karlsruhe.eu\/wp-content\/uploads\/2022\/06\/Photomath_2022_Dhruv-1024x692.jpg 1024w, https:\/\/www.es-karlsruhe.eu\/wp-content\/uploads\/2022\/06\/Photomath_2022_Dhruv-768x519.jpg 768w, https:\/\/www.es-karlsruhe.eu\/wp-content\/uploads\/2022\/06\/Photomath_2022_Dhruv-1536x1038.jpg 1536w, https:\/\/www.es-karlsruhe.eu\/wp-content\/uploads\/2022\/06\/Photomath_2022_Dhruv.jpg 1772w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><\/a>\n\t\t\t<\/dt><\/dl>\n\t\t\t<br style='clear: both' \/>\n\t\t<\/div>\n\n","protected":false},"excerpt":{"rendered":"<p>I captured this beautiful phenomenon at dusk from my balcony.
