Quizplus · Accepted Answer

The color of the sky is determined by the scattering of light by air molecules. Blue light has a shorter wavelength and is scattered more easily than red light, which has a longer wavelength. If air molecules selectively scatter only the longest wavelengths of visible light, then the blue light would be absorbed, leaving only the longer wavelengths such as red, orange, and yellow. Therefore, the sky would appear red in color.
