Rayleigh scattering of blue light
WebApr 10, 2024 · In the simplest case of normal light incidence and a homogeneous environment or surrounding nanoparticles with an infinite half-space of a particular material, the longest wavelength of Rayleigh anomaly is equal to the periodicity of the lattice multiplied by the refractive index of the surrounding medium, i.e., \(\lambda _{\text {RA}} = … WebFor example, when light from the sun travels through the atmosphere, it has interactions with the molecules in the air and is therefore dispersed in all directions. The color of the sky is due to a process known as Rayleigh scattering, which gives the impression that the sky is …
