Vedclass · Answer

(B) The molecules of air and other fine particles in the atmosphere have a size smaller than the wavelength of visible light. These particles are more effective in scattering light of shorter wavelengths at the blue end of the spectrum than light of longer wavelengths at the red end. As blue light has a shorter wavelength,it gets scattered the maximum by the atmospheric particles,which makes the sky appear blue to our eyes.
