Question

it name the sun appear as white but morning and evening appear was radiusl?
​

Answer 1

Explanation:

It is due to scattering of light. At noon, the sun is at the nearest point to earth. Hence all the colors get scattered almost equally and this you see white light.

But during sunrise and sunset, the sun is at the longest position. Here blue light gets scattered off and due to larger wavelength of the red light it can travel a longer distance and hence reach our eyes. This we see the sun red.
