why does sun appears reddish early in morning
Answers
The atmosphere consists of free molecules and atoms with different sizes. These molecules and atoms scatter light of different wavelengths which are comparable to their size. Molecules having a size that is comparable to the wavelength of red light are less in the atmosphere. Hence scattering of red light is less when compared to the other colors of light. The light from the sun needs to travel more distance in atmosphere during sunrise and sunset to reach your eye. In morning and evening times, during sunrise and sunset, except red light all colors scatter more and vanish before they reach you. Since scattering of red light is very small, it reaches you. As a result sun appears red in color during sunrise and sunset.
