Meaning of Rayleigh scattering in English:

Rayleigh scattering

Pronunciation

noun

mass nounPhysics
  • The scattering of light by particles in a medium, without change in wavelength. It accounts, for example, for the blue colour of the sky, since blue light is scattered slightly more efficiently than red.

    Compare with Raman effect

    ‘This led us to shift the excitation to a lower wavelength to minimize the contribution from Rayleigh scattering in the emission spectra.’
    • ‘Additionally, there may be significant scattering by the various species present, including Rayleigh scattering by particles smaller than the wavelength of light.’
    • ‘At these wavelengths, Rayleigh scattering is also reduced, increasing visual clarity.’
    • ‘The red colour in the sky at sunset is due to an effect called Rayleigh scattering.’
    • ‘Based on Rayleigh scattering, the sensor can be used to monitor perimeters around secure facilities and prisons.’
