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 (diffraction pattern) at the edge of a shadow.
the bending of waves, especially sound and light waves, around obstacles in their path.

Diffraction - HyperPhysics


Diffraction. Diffraction manifests itself in the apparent bending of waves around small obstacles and the spreading out of waves past small openings.

Tell us your email address: Definition: A modification which light undergoes, as it passes by the edges of opaque bodies or through narrow slits. The rays appear to be deflected, producing fringes of parallel bright and dark bands. Definition Copyright ©1989 CRC Press... More »
