A “zero shadow day” is a day when vertical objects appear to cast no shadows. This is because the sun is at its zenith and the shadow is directly below the object.
There are two Zero Shadow Days each year at every point on Earth between the Tropic of Capricorn and Capricorn.of zero shadow day Restricted to locations between the tropics. Areas north of Ranchi in India are not covered.
Uttarayan (the movement of the sun from south to north from the winter solstice to summer solstice) and Dakshinayan (the movement of the sun back from north to south) occur when the Earth’s axis of rotation is tilted at an angle of approximately 23.5° to the axis of its revolution around the sun. It happens because.
Day zero occurs in all locations where the latitude is equal to the angle between the sun’s position and the equator on that day, and there is a shadow below the object at local noon.
Bangalore must have witnessed a zero shadow day between 12:17 pm and 12:23 pm today. Places at the same latitude as Bangalore must have experienced it as well. Residents of Kanyakumari, Bhopal, Hyderabad and Mumbai are also likely to witness this phenomenon today.
A similar incident happened in Tamil Nadu as well. Kodaikanal April 16th.
The Indian Institute of Astrophysics (IIA), Bangalore, today organized an event at its Koramangala campus to commemorate Zero Shadow Day. The public was also welcomed to participate in activities starting from 10 a.m. to 1 p.m.
See how people observed the day through videos and posts on social media.
“On April 24th, celebrate Zero Shadow Day for locations in Bengaluru latitude. Measure the length of your shadow and check out the cool demo. We collaborate with Bhopal and Chennai to find Earth’s diameter and its rotational speed,” the Indian Institute of Astrophysics said in a social media post.
Bengaluru had also recorded a zero shadow day last year. The shadow of the vertical object momentarily disappeared at 12:17 pm on April 25th.
