WebSolution. Rayleigh scattering is the scattering of light by the particles present in the atmosphere. According to Rayleigh's scattering law, the amount of scattering of the light is inversely proportional to the fourth power of the wavelength. From the relation between scattering and wavelength, we understand that shorter wavelengths scatter more. WebRayleigh's Criterion is usually applied to circular apertures, where the criterion for resolution is when the center of one Airy disk pattern falls on the first minimum of the Airy disk pattern of the second source. The angular separation θ is then. θ = ( 1.22 λ ) / D. where λ is the wavelength of light, and D the aperture diameter. green financial kirkland wa https://ctemple.org
