WebIn fluid mechanics, the Rayleigh number ( Ra, after Lord Rayleigh [1]) for a fluid is a dimensionless number associated with buoyancy -driven flow, also known as free (or … WebThe Rayleigh ratio Rθ is the ratio of the scattered to incident light intensity, corrected for the size of the scattering volume and the distance of the detector from the scattering volume. 𝑅𝜃= 𝐼𝜃𝑟2 𝐼0𝑉 (1) Where Iθ is the scattered intensity at angle θ, I 0 is the incident intensity, r is the distance from the scattering

WebStatic light scattering is a technique in physical chemistry that measures the intensity of the scattered light to obtain the average molecular weight M w of a macromolecule like a polymer or a protein in solution. Measurement of the scattering intensity at many angles allows calculation of the root mean square radius, also called the radius of gyration R g. slumberland furniture moorhead mn
