Solution
Verified by Toppr
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.
However, light from the Sun overhead would
travel relatively shorter distance. - At noon, the Sun
appears white as only a little of the blue and violet
colours are scattered.
- 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.
