In fact this happens completely spontaneously and suddenly like the twin boundary formation at low temperatures (i.e., massive transformations). Atmospheric coherence times in interferometry: definition and measurement. Without coherence, a discussion may not make sense or may be difficult for the audience to follow. The most common dictionary definition is the quality of being logically integrated, consistent and intelligible, as in a coherent statement. If something has coherence, its parts are well-connected and all heading in the same direction. Coherence has several related definitions, all of which are applicable to the study of human physiology, social interactions and global affairs. In the final stage where the overall system reaches to the non-equilibrium stationary state, the CSL interface may be transformed into the semi-coherent type boundary by the formation of dislocation array at the interface to accommodate the large stored strain energy associated with long range distortion of lattice planes (The Strain Relaxation Phenomena SRP)) by the dislocation core energies. Coherence describes the way anything, such as an argument (or part of an argument) hangs together. noun 12 2 A property holding for two or more waves or fields when each individual wave or field is in phase with every other one. An example of coherence is an argument that has no inconsistencies. Best online English dictionaries for children, with kid-friendly definitions, images, and animations. Even though this type of boundary may have transient existence but still it is important for the initiation of Stranski-Krastanow islanding (Q-Dots) on the rough surfaces of the hetero-epitaxially strained thin films. The definition of coherence is something logical or consistent and something that makes sense as a whole. 1 : a property of electromagnetic waves that have a definite phase relationship to each other.

SMART Vocabulary: related words and phrases. This process is experimental and the keywords may be updated as the learning algorithm improves.Dear Professors Butler and Agren, as a physical metallurgist we some how have relaxed the definition of coherency by allowing some reasonable distortions (small mismatch strain in the range of 0.1-0.05% )otherwise perfectly planar LP to include the Coincidence Site Lattice boundaries in the same category. the situation when the parts of something fit together in a natural or reasonable way: There was no coherence between the first and the second half of the movie. These keywords were added by machine and not by the authors. This manuscript will provide a brief overview of the concept of coherence, from a classical description of Young’s experiment, to a quantum mechanical definition of coherence. Coherence is a state or situation in which all the parts or ideas fit together well so that they form a united whole. As our understanding of electro-magnetic radiation grew, the idea of coherence developed beyond this original definition. What is Coherence Definition of Coherence: The various concepts and measurements embraced under the term coherence have become central to fields as. The term coherent was applied to describe light that would produce interference in an experiment like Young’s. What does coherence mean Proper usage and audio pronunciation (plus IPA. coherence - Meaning in Hindi, what is the meaning of coherence in Hindi dictionary, pronunciation, synonyms, usage examples and definitions of coherence in. Also, light from some sources would not produce interference at all. Definition of coherence in the Dictionary. It was found that in order to produce an interference pattern, the two beams had to come from the same source.

While this phenomena supported the wave nature of light, another more interesting fact was uncovered. The idea of coherence dates to Young’s Experiment where is was shown that two beams of light could interact and produce an interference pattern on a distant screen.
