"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. " - Rayleigh scattering technique
