Rayleigh scattering

Physics

See scattering of electromagnetic radiation.

Astronomy

The scattering of light by particles much smaller than the wavelength of the light. The amount of scattering increases as the wavelength gets shorter, so blue light is scattered more than red light. The incoming beam is scattered equally forwards and backwards. Rayleigh scattering of sunlight by molecules in air is the cause of the blue colour of the daylight sky. It is named after the English physicist Lord Rayleigh (1842–1919).

Chemistry

Scattering of electromagnetic radiation by molecules in which the frequency of the scattered radiation is unchanged. This type of scattering was analysed by Lord Rayleigh in his papers in the late 19th century, which showed that the blue colour of the sky is a result of this type of light scattering, with molecules of the atmosphere of the earth scattering light from the sun.

Geology and Earth Sciences

The scattering of electromagnetic radiation by spherical particles with radii that are less than 10% that of the wavelength of the incident radiation. Such scattering by air molecules produces the blue effect of the sky. Particles such as dust and smoke, that are significantly smaller than 0.4μ‎m (the wavelength of the blue/violet or lower limit of the visible spectrum) can also scatter visible radiation. Reddish colours at sunset and sunrise result from Rayleigh scattering; these longer wavelengths pass directly through the atmosphere to the observer, while particles in the air scatter out radiation of shorter wavelengths. See also mie scattering.
