Incoherent waves
WebCoherent Waves: Coherence is attained when there is a constant phase difference in two or more waves over time. Two waves are said to be… WebIf the plane waves or momentum eigenstates have a well-defined phase relationship, the atomic ensemble may be described by a wave packet. A continuous beam experiment cannot distinguish between a coherent superposition of plane waves (wave packet) and an incoherent superposition as in Eq. (10). Therefore, we are free to choose whether we use ...

See more 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. … See more Coherence was originally conceived in connection with Thomas Young's double-slit experiment in optics but is now used in any field that involves waves, such as acoustics, electrical engineering, neuroscience, and quantum mechanics. Coherence … See more These states are unified by the fact that their behavior is described by a wave equation or some generalization thereof. • Waves in a rope (up and down) or slinky (compression and expansion) • Surface waves in a liquid See more In some systems, such as water waves or optics, wave-like states can extend over one or two dimensions. Spatial coherence describes the ability … See more The coherence function between two signals $${\displaystyle x(t)}$$ and $${\displaystyle y(t)}$$ is defined as See more The coherence of two waves expresses how well correlated the waves are as quantified by the cross-correlation function. Cross-correlation … See more Temporal coherence is the measure of the average correlation between the value of a wave and itself delayed by τ, at any pair of times.
