  2. QUESTION What is diffraction ?

  3. Answer • The process by which a beam of light or other system of waves is spread out as a result of passing through a narrow aperture or across an edge, typically accompanied by interference between the wave forms produced this scattering form of wave is called diffraction.

  4. 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.

  5. Diffraction photography was used in spectroscopy to help record the chemical composition of objects studied by astronomers . • Diffraction refers to the process by which a beam of light or other system of wave is spread out as a result of passing through a narrow aperture or across an edge. The waves are typically accompanied by interference between the wave forms produced.

  6. The formalism of diffraction can also describe the way in which waves of finite extent propagate in free space. For example, the expanding profile of a laser beam, the beam shape of a radar antenna and the field of view of an ultrasonic transducer can all be analyzed using diffraction equations.
