Rayleigh scattering (named after Lord Rayleigh) is the scattering of light, or other electromagnetic radiation, by particles much smaller than the wavelength of the light. It occurs when light travels in transparent solids and liquids, but is most prominently seen in gases. Get answers by asking now. Still have questions?

Several people have sent in photos of the sun in the sky, especially at sunrise and sunset. I keep expecting four blokes on horses to home galloping out of the sky. When light (or more specifically, packets of light called photons) from an astronomical object passes through the Earth's atmosphere, it scatters off of particles in the latter. Its easy in mornings or evenings the light rays from the sun has to travel a long distance than it does at noon so the atmosphere absorbs all the blue light and difracts only the red end of the spectrum so the sky and the sun appears red in dawn and dusk.
