wave coherence
1Coherence bandwidth — is a statistical measurement of the range of frequencies over which the channel can be considered flat , or in other words the approximate maximum bandwidth or frequency interval over which two frequencies of a signal are likely to experience… …
2Coherence (physics) — In physics, coherence is a property of waves that enables stationary (i.e. temporally and spatially constant) interference. More generally, coherence describes all properties of the correlation between physical quantities of a wave. When… …
3Coherence time — For an electromagnetic wave, the coherence time is the time over which a propagating wave (especially a laser or maser beam) may be considered coherent. In other words, it is the time interval within which its phase is, on average, predictable.… …
4Coherence length — In physics, coherence length is the propagation distance from a coherent source to a point where an electromagnetic wave (or wave packet, wave function, etc.) maintains a specified degree of coherence. The significance is that interference will… …

6Atomic coherence — In physics, atomic coherence is the induced coherence between levels of a multi level atomic system sometimes observed when it interacts with a coherent electromagnetic field.If a coherent, narrow bandwidth laser is applied to a two level system …
7Degree of coherence — In optics, correlation functions are used to characterize the statistical and coherence properties of an electromagnetic field. The degree of coherence is the normalized correlation of electric fields. In its simplest form, termed g(1), it is… …
8Interference (wave propagation) — Two point interference in a ripple tank. In physics, interference is the phenomenon in which two waves superpose each other to form a resultant wave of greater or lower amplitude. Interference usually refers to the interaction of waves that are… …
