ln physics , two wave sources are perfectly coherent if they have a constant phase difference and the same frequency .lt is an ideal property of wave that enable stationary ( i.e. temporarlly and spationally constant )interference.
Two sources are said to be coherent when the Waves emitted from them have the same frequency and constant phase difference . lnterference from such waves happen all the time, the randomly phased light wave constantly produce bright and dark fringes at every point .
