Question

89) which of the following molecules in atmosphere are responsible for blue color of sky?

Answer 1

The molecules of air and other suspended particles in air like dust...tiny water droplets are present in the sky.....When light enters the ssky the light scatters the shorter wavelength more effectively than that of longer wavelengths.....Blue which is of shorter wavelength as a result is scattered the most....And this blue colour reaches our eyes and as a result we see the sky blue.....

Answer 2

Our atmosphere contains different types of molecules and atoms. The resin fur blue sky is due the molecules of N2 and O2. The dudes of molecules are comparable to the wavelength of blue light. These molecules act as scattering cents for scattering of blue light.
