Think of a high angle grain boundary. The structure is very disordered there and bonds have been broken. Thus, the interface is unstable and high in energy. Thus, coherence leads to lower interfacial energies. The degree of coherence dictates the interfacial energy, so the most coherent interface will have the lowest interfacial energy.
The term interfacial tension or surface tension means the contractive tendency of a liquid that lets it resist and external force. Interfacial tension could be observed from the floating of objects on the surface of water, even though they are more dense than water.
so term in volt be it millivolt or petavolts it will vary on energy
Fiber optic lasers can have coherence lengths greater than 100 km. Helium-neon lasers can produce light with coherence lengths greater than 5 m but 20 cm is typical. Laser diode chips are a fraction of a mm on a side and so coherence lengths on that order are expected, however some of the cheapest laser pointers can produce coherence lengths of 20 cm for short intervals of time and have been used to create holograms. In general the length depends on many variables. The typical red light laser diode (λ= 650 nm) with a frequency stabilizer can have a coherence length of over 1 m. LEDs have a spectra width Δλ of about 50 nm, and may have a coherence length of 10's to 100's of μms. As a side note, because the exited states of the atoms in a tungsten filament are short lived, the coherence length is only a few micrometers (μm). Some notes about coherence lengths: Interference is only visible if the coherence length of the light is at least as long as the path-length difference that creates the interference. Spectral width in optics is related to coherence length by the formula L = λ²/(nΔλ) where λ is the central wavelength, n is the index of refraction and Δλ is the spectral width. The coherence time is the above coherence length divided by the light's phase velocity in the medium or.. τ = λ²/(cΔλ) Refer to the Related link below for Wikipedia's article on coherence length
You are asking two Questions at once: How does the energy of the different waves of the spectrum vary with frequency? and How does the energy of the different waves of the spectrum vary with wave length? f (Frequency) = c / Lambda.
Coherence is a measure of how well a signal, such as a optical wavefront, correlates with itself. For example, if you measure a peak at one point in space and time, what is the chance that you will measure a peak at another space and time? This hints that there are actually two forms of coherence, one related to time and the other to space.Temporal coherence looks at how well radiation measured at one single point correlates over time. In other words, if you measure a peak at one moment in time, how well can you predict that you'll measure a peak at another moment in time? Temporal coherence generally requires a small spread in wavelengths and a source which emits light in-phase. Lasers typically have high temporal coherence, while sunlight, which has a broad emission spectrum, has a low temporal coherence.But that's not the end of the answer.The other type of coherence is spatial coherence, and relates to how well two points on an emitter are correlated. One classic way of demonstrating spatial interference is the double-slit experiment: put two small slits in a sheet, and check to see that the light from the slits interferes constructively. Spatial coherence generally requires a small degree of angular spread. Again, most lasers have high spatial coherence. Sunlight also has high spatial coherence: because the sun is so far away, the rays of light are almost parallel.The coherence of sunlight has been studied since 1869 (Agarwal et al, "Coherence properties of sunlight", Optics Letters 29, p. 459, 2004) -- but even with more than a century of coherence, the subtle difference between spatial and temporal coherence can be tricky.
What is the interfacial properties of surfactant solution?
coherence in sentance
when two material are brought to contact,so the space where they made contact is called interfacial area,it is usually considered in heat transfer calculation
The term interfacial tension or surface tension means the contractive tendency of a liquid that lets it resist and external force. Interfacial tension could be observed from the floating of objects on the surface of water, even though they are more dense than water.
The coherence of the party made me in confusion as whom to vote. This is an example of coherence in a sentence.
It is the phase, which can be measuerd with these type of coherence.
Unity refers to the overall focus or theme of a text, including how all parts of the text relate to that central idea. Coherence, on the other hand, refers to the clarity and logical connection between ideas, sentences, and paragraphs within a text. In essence, unity focuses on the big picture theme, while coherence focuses on the organization and flow of the text.

Interfacial velocity is the speed of a fluid whose movement is generated by its mass transfer from a phase to the next . Another factor that generates interfacial velocity is the bulk motion of the fluid, known as advection.
Transition metals vary in the number of electrons in the highest level. Alkaline earth metals have two electrons in the highest energy level.
There are two types of coherence time and space coherence. Time coherence means that the wave phase stays constant in time. Space coherence is when the wave phase is a constant when light travels in space. Both are really important and can be found in lasers and other sources of electromagnetic radiation.
