Expert Answer:

Dear student
Light from the Sun near the horizon passes
through thicker layers of air and larger distance
in the earth’s atmosphere before reaching our eyes.
Near the horizon, most of the blue light and shorter
wavelengths are scattered away by the particles. Therefore, the light that reaches our
eyes is of longer wavelengths. This gives rise to the reddish appearance
of the Sun.
Hope this helps.
