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 WebIncoherent Sources of waves The waves are said to be incoherent if they do not have constant phase difference. These sources will produce light with random and frequent changes of phase between the photons. For example, ordinary fluorescent tubes and Tungsten filament lamps produces incoherent light waves.
