The most general form of Cauchy's equation is where n is the refractive index, λ is the wavelength, A, B, C, etc., are coefficients that can be determined for a material by fitting the equation to measured refractive indices at known wavelengths. The coefficients are usually quoted for λ as the vacuum wavelength in micrometres. Usually, it is sufficient to use a two-term form of the equation: WebUsers enter the refractive index of the medium (typically air or water) and the refractive index of the particle. This is simply the refractive index of the particle divided by the refractive index of the dispersion medium. If n = 1.33 (water) and n’ = 1.60 (particle), then the relative refractive index is 1.60/1.33 = 1.203. chrysantheme blaubeer komplex
