Abstract

VI.

THE diagrams given in my last article should have made it quite clear that the various sunset and sunrise colours are due to the absorption produced by different thicknesses of aqueous vapour; that the colours of clouds are due to light falling upon them after absorption by different thicknesses of aqueous vapour; and finally that the blue colour of the sky in the zenith is due to the fact that the pure gases in our atmosphere exist in that molecular grouping which vibrates in harmony with the short waves of light.
