Scattering of light

Vedclass · Answer

(B) At sunrise or sunset,the sun is near the horizon. Light from the sun has to travel a much larger distance through the atmosphere to reach the observer. During this journey,most of the blue and shorter wavelengths of light are scattered away by the atmospheric particles. Only the light of longer wavelengths,such as red,is able to reach our eyes. Therefore,the sun appears reddish at sunrise or sunset due to the scattering of light.

Which of the following phenomena contributes significantly to the reddish appearance of the sun at sunrise or sunset?
