WebDiffraction definition, the phenomenon exhibited by wave fronts that, passing the edge of an opaque body, are modulated, thereby causing a redistribution of energy within the front: … WebIn general, however, diffraction leads to changes of the shape of the intensity profile, as can be seen e.g. in Figure 1. Laser beams are often diffraction-limited, i.e., their expansion during propagation is not stronger than caused by diffraction alone. Strong diffraction effects occur for light with long wavelengths.
