State the difference in colour of the sun observed during sunrise/sunset and noon. Give explanation for each.

Difference in colours of the sun at sunrise/sunset and at noon are as follows :
(i) Sunrise/Sunset: Reddish in colour
Reason: Sunlight travels longer distance at this time of the day, so the short wavelength colours get scattered away and the sunlight is left with only longer wavelength light which is reddish or orange. So the sun appears reddish in colour,

(ii) Noon: White in colour
Reason: Sunrays travel shorter distance at noon and contains all the wavelengths of light which combine to form white colour. This makes the colour of sun white.
