DiffractionĪround apertures is described approximately by a mathematical formalism called scalar diffraction theory.ĭiffraction problems are among the difficult encountered in optics, and exact rigorous solutions are quite rare. Diffraction - from Eric Weisstein's World of Physicsĭiffraction is a phenomenon by which wavefronts of propagating waves bend in the neighborhood of obstacles.
