Rayleigh scattering The scattering of light by particles that are small in relation to the wavelength of the light. Rayleigh scattering of short wavelengths in sunlight by gas molecules in the atmosphere is the reason the sky appears blue. The phenomenon is named after the English physicist Lord Rayleigh (1842-1919).
