Rayleigh limit scatering
WebThe name “Rayleigh scattering” is mostly associated with light scattering by molecular and atomic gases and the related question “Why is the sky blue?”1,2 In addition, the name Rayleigh is commonly attached to scattering by small particles in the expressions “Rayleigh regime” or “Rayleigh limit,” in which small refers to a size ... WebFeb 7, 2015 · When the size of a structure under a conventional optical microscope is slightly smaller than the Rayleigh limit, the intensity decreases rapidly to the point of it becoming no longer visible. This can be described in terms of Rayleigh scattering, in which the object size d < < λ and the intensity of the scattered light decreases as a function of d 6 .
