explain the blue color of the sky.

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.
