Expert Answer
Dear student
The molecules of air and other fine particles in the atmosphere have size
smaller than the wavelength of visible light. These are more effective in
scattering light of shorter wavelengths at the blue end than light of longer
wavelengths at the red end. The red light has a wavelength about 1.8
times greater than blue light. Thus, when sunlight passes through the
atmosphere, the fine particles in air scatter the blue colour (shorter
wavelengths) more strongly than red. The scattered blue light enters
our eyes.
Hope this clarifies your doubt.
