Fraunhofer distance

ID: fraunhofer-distance

The Fraunhofer distance is a concept used in optics, particularly in the study of wave propagation and diffraction patterns. It refers to the distance from a wave source at which the wavefronts can be considered parallel, and thus the far-field approximation can be applied. This approximation simplifies the mathematical treatment of the wave behavior, especially when analyzing diffraction patterns.
