Draw a labelled diagram to show (i) reddish appearance of the sun at the sunrise or the sunset and (ii) white appearance of the sun at noon when it is overhead.

(i) The diagram demonstrates the reddish appearance of sun due to the phenomena of scattering of light

(ii) When the sun is nearly overhead than the light emerging from the sun undergoes less scattering compared to when the sun is at the horizon. Hence appears to be white.
