While remaining accurate under the first-order Born approximation and the paraxial assumption, the scattering of a Young's diffractive electromagnetic light wave by a quasi-homogeneous (QH) medium is specifically addressed in this study. Analytical expressions are derived for spectral density as well as the spectral degree of coherence of the scattered field. As long as the components of the complex amplitude of incident waves are proportional to each other, the resultant scattered light in the
