http://web.mit.edu/2.710/Fall06/2.710-wk10-a-sl.pdf WebJan 20, 2024 · * Diffraction Diffraction is a phenomenon in which a wave spreads from the end of a small gap or returns to the shadow of an obstacle. Huygens principle is the principle that countless spherical waves are generated at each wavefront point, and the wavefront of the next moment is created by overlapping the countless spherical waves. When the …

Fraunhofer Diffraction vs Fresnel Diffraction

WebNov 7, 2015 · Types of Diffraction. Diffraction phenomenon can be divided into following two general classes: 1. Fraunhofer’s Diffraction: In this class of diffraction source and the screen are placed at infinity. In this case the wavefront which is incident on the aperture or obstacle is plane. WebDiffraction can be classified as Fresnel or Fraunhofer (also called far field diffraction). In Fraunhofer diffraction the distance between the aperture and the screen is large enough to treat the wavefront as planar. In Fresnel diffraction the wavefront has to be treated as a curved surface. WebFor a further simplified case, valid only for much larger distances from the diffraction source, see Fraunhofer diffraction.
