  1. 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: it is detectable in light waves by the presence of a pattern of closely spaced dark and light bands at the edge of a shadow.
  2. the bending of waves, especially sound and light waves, around obstacles in their path.
