WebNov 21, 2024 · If light is spatially coherent, the source is physically very small. In an interferometer using light of high temporal coherence and high spatial coherence, interference fringes can form even if the two beams in the interferometer travel paths of substantially different lengths. WebIncoherent Source. Conventional light sources are used to produce incoherent sources. An incoherent source emits a light wave having a different frequency, wavelength and phase. In these waves, the transitions between energy levels in an atom is a completely random process. Hence, no control can be established over an atom that is going to lose ...

In physics, two wave sources are coherent if their frequency and waveform are identical. Coherence is an ideal property of waves that enables stationary (i.e., temporally or spatially constant) interference. It contains several distinct concepts, which are limiting cases that never quite occur in reality but allow an understanding of the physics of waves, and has become a very important concept in quantum physics. More generally, coherence describes all properties of the correlation
