Question

Who do the clear sky appear blue during noon?

Answer 1

at noon , sun is directly above our head , so we get the light rays directly from sun after travelling the shortest distance , without much scattering of any particular colour . hence the sky is noon

Answer 2

A cloudless clear day-time sky looks blue in colour because particles in the air completely disseminate blue light coming from the sun ray more than these particles can scatter other colours.

The white sunray contains all 7 lights including blue, and the blue colour more than any other colours moves around in shorter and tiny waves.

During noon the availability of sunrays are the highest and that’s why the sky looks blue.
