As white light passes through our atmosphere, tiny air molecules cause it to ‘scatter’. The scattering caused by these tiny air molecules (known as Rayleigh scattering) increases as the wavelength of light decreases. Violet and blue light have the shortest wavelengths and red light has the longest. Therefore, blue light is scattered more than red light and the sky appears blue during the day. When the Sun is low in the sky during sunrise and sunset, the light has to travel further through the Earth’s atmosphere. We don’t see the blue light because it gets scattered away, but the red light isn’t scattered very much – so the sky appears red.
You have changed the way I see the sky, I've always thought that it were to be purple... but ever since i saw this now i realize that it is indeed, Blue.
damn i thought id be the one explaining :c Anyways, IN SHORT, light go br through air we breth and blue
