noun[mass noun] Physics
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.
