Question

Define Indivisibility of stations.

Answer 1

When white light incident upon earth's atmosphere, it's colours are scattered by the air particles in accordance with Rayleigh Scattering ( i.e. scattering is inversely proportional to fourth power of wavelength ) . Hence ,in the seven colours of white light,blue colour has the smaller wavelength and hence it is least scattered while other wavelengths are scattered away by earth's atmosphere
