Have you noticed the Sun during Sunrise or Sunset?

It appears red


But, in the afternoon, it appears white.


Let's see why it happens


During Afternoon

Sun is directly above us

Light rays from Sun take lesser time to reach us

Hence there is less scattering of blue light

So Sun appears to be white


During Morning and Evening

Sun is at the horizon

Light rays from sun take more time to reach us

Hence, there is more scattering of blue color of sunlight which is of shorter wavelength

Hence we are able to see red colored sun because there is less scattering of red color
