text: Rayleigh scattering of sunlight by atmospheric molecules is the reason for the observed blue color of the sky, because the scattering efficiency varies inversely with the fourth power of the wavelength.
text: For example, Rayleigh scattering is the reason the sky looks blue: the intensity of the light that gets Rayleigh scattered by a molecule is inversely proportional to the fourth power of the wavelength of the incident light, which means that 10 times more blue light than red light gets scattered from a molecule.
text: Rayleigh scattering of sunlight from particles in the atmosphere is the reason why the light from the sky is blue.
