Question

why sun is red at noon time​

Answer 1

as its hotness is more to the people in the equator

Answer 2

$\huge\bf\red{Hey\:Mate..!}$

This is due to phenomenon called as scattering of light. At noon sun is directly overhead so the light rays coming from sun absorb all the visible colours thats why we see sun white coloured. But in evening sun is far away as compared to noon. Light rays scattered due to dust particles present in atmosphere, dust particles absorb all the colours except red. So more is the dust in atmosphere more is scattering of red colour thats why we see sun and its surrounded place reddish.

This phenomenon is also shown theoretically by Rayleigh’s Criteria.
