- the act or condition of cohering; cohesion
- the quality of being logically integrated, consistent, and intelligible; congruity: his story lacked coherence
- Physics that property of a set of waves or sources of waves in which the oscillations maintain a fixed relationship to each other
Origin of coherenceFrench ; from Classical Latin cohaerentia ; from cohaerens, present participle of cohere

coherence - Computer Definition
From the Latin co- (together) and haerere (to stick), translating as sticking together. 1. The property of a set of electromagnetic waves, consistently similar in terms of a feature such as polarization or phase. Signals consistently synchronized in phase are characterized by oscillations that maintain a fixed relationship, with the sine waves rising and falling in unison. See also phase, polarization, and sine wave. 2. The property of a light source that fires within a narrow range of wavelengths, ideally only one, so that all photons act identically. See also wavelength and window.
