| The intensity of the scattered light on the molecules of the Earth’s atmosphere is inversely proportional to the fourth power of the wavelength (Rayleigh’s law). Why, then, does the sky appear blue and not purple?
The sun emits little in the violet region of the spectrum, and human eyes are mainly sensitive to the yellow-green region.
