Coherence, coherency, or coherent may refer to the following:

PhysicsEdit

  • Coherence (physics), an ideal property of waves that enables stationary (i.e. temporally and spatially constant) interference
  • Coherence (units of measurement), a derived unit that, for a given system of quantities and for a chosen set of base units, is a product of powers of base units with no other proportionality factor than one
  • Coherence time, the time over which a propagating wave (especially a laser or maser beam) may be considered coherent; the time interval within which its phase is, on average, predictable
  • A system of units is Said to be Coherent ,if all the derived units can be obtained by multiplying or dividing its fundamental units such that no numerical factors are introduced.

MathematicsEdit

PhilosophyEdit

  • Coherentism, philosophical theories in modern epistemology, the study of knowledge
  • Coherence theory of truth, a theory which regards truth as coherence within some specified set of sentences, propositions or beliefs
