    Sky appears blue because the size of the atmospheric particles is nearly same as the wavelength of the blue light .Due to this blue light is scattered more......

    1Thank You

    Aayushi Bhandari 6 years, 5 months ago

    It is so because particles in the atmosphere reflect the light of blue wavelength more than any other

    0Thank You

    Ron Vineetahuja 6 years, 5 months ago

    Because wavelength of blue color is very small and according to Raleigh's criteria Scattering is inversly proportional to fourth power of wavelength. So wavelength is small its scaterrs more so due to this reason sky look blue

    Blue light scatters the most in all colours because it travels as shorter, smaller waves. Blue light is scattered in all direction by tiny molecules of air in earth's atmosphere.
