Diffraction
Another significant propagation mechanism is diffraction, which allows radio signals to travel around around obstructions. It can be explained by Huygen's ... 
Diffraction : Taking Light Apart - McDonald ObservatoryInterference and diffraction are common phenomena intrinsic to wave propagation. Interference refers to the effects caused by the coherent addition of wave ... DiffractionThe tendency of diffraction to expand the smallest structure into the largest pattern is the key to the technique of x-ray crystallography, in which x-rays ... Chapter 5: Interference and DiffractionWhen we deal with highly coherent light, such as from lasers, diffraction and interference effects become much more prominent than usual. ... called diffraction. 31. Diffraction: a few important illustrationsThe wave/physical optics behavior of any wave that encounters an obstacle. ? It is closely related to interference in terms of how the downstream waves, ... Chapter 5: Diffraction. Say a wave arrives at an. opaque screen with a little hole in it. On the other side of the screen, the wave equation must. still be satisfied with boundary conditions given by the motion of the wave in the hole.
