Why do we observe difference in colours of the sun during sunrise, sunset and noon?
Solution
During the sunrise or sunset, the sun is at horizon. Most of the blue light and other light of shorter wavelength are scattered most. Only the longer wavelength (red) reaches to us. That’s why sun appears red during the sunrise or sunset. At noon, the Sun appears white because it is at our head and all wavelength reaches to us due to little of the blue and violet colours are scattered due to least distance travelled by fight.
