WebDespite the elastic nature of Rayleigh scattering, the feedback mechanism has been insofar deemed incoherent, which corresponds to the commonly observed smooth generation spectra. Here, using a real-time spectral measurement technique based on a scanning Fabry-Pérot interferometer, we observe long-living narrowband components in the random … WebApr 4, 2024 · The Rayleigh-Gans-Debye theory is valid in the region A/20 < 2a < A, where the radiation envelope will become asymmetrical with more light being scattered forward (9 < 90°) than backward (90° < 9 < 180°). The light scattering intensity at 90° is much less than the intensity at the forward (0°) angle due to destructive interferences. greats pronto
