WebJun 24, 2016 · The word "coherent" is used in Physics in a rather sloppy way. Your first state is a linear combination of harmonic oscillator eigenvectors that turns into a gaussian in momentum/position representations. WebIn light: Young’s double-slit experiment. Such light is called incoherent. Interference still occurs when light waves from two incoherent sources overlap in space, but the interference pattern fluctuates randomly as the phases of the waves shift randomly. Detectors of light, …

17.2 Applications of Diffraction, Interference, and Coherence

WebCoherence In wave optics, we make a distinction between coherent and incoherent sources of light. Any real source of light is not exactly monochromatic (single color), but has a range or band of frequencies, Δ f. An incoherent source of light lacks a specific direction and has a relatively large Δ f. By contrast, a coherent source has a specific direction with a much … WebThose photons could go on to hit other excited atoms, and soon you would have a stream of in-phase photons.
