Vector models of this phenomenon include one based on the surface equivalence principle, and its propagation can be modeled by applying Green's theorem to the Helmholtz wave equation. Scalar theories of this phenomenon include Rayleigh-Sommerfeld theory, and its (*) Fraunhofer variety occurs for Fresnel numbers significantly less than one. Its occurrence for X-rays passing through a crystal structure is given by Bragg's law in X-ray crystallograp
