The blue sky spectrum … WebQuestion: Sunsets are a deep red because tiny particles in the air are more efficient at scattering short wavelength light than they are at scattering long wavelength light. Hence, long wavelength light ends up coming directly towards you. most polluting gases and dust particles in the air are reddish in color and lend their color to that of the sky air molecules WebAnswer 1: Both the sky and the ocean are blue, but for two very different reasons. The sky is blue because of something called Rayleigh scattering. For very small particles such as individual molecules, the wavelength of light that is reflected is a function of the particle size and type of molecular bonds between atoms. laird lambert
