I don't think so. Coherence is defined for light of a single wavelength.

What is the relation between wave length and the color of light?
Different colors have different wavelengths
Is sun light coherence source?
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 wavelengths of light can humans see?
Most humans eyes are sensitive to wavelengths between about 400 nm (violet) and 700 nm (red)
What wave lengths is closest to the wave length of red light?
Visible light wavelengths fill the electromagnetic spectrum between red wavelengths and violet wavelengths.
What is the difference between diffraction and dispersion?
Diffraction = The amount of light passing through a photographic lens being adjusted by a diaphragm. Dispersion = The splitting of light of different colors due to the different indices of refraction at different wavelengths when the light enters a lens or prism.
Is it possible to coherence between light sources emitting light of different wavelengths?
I don't think so. Coherence is defined for light of a single wavelength.
What is the difference between coherence and adherence?
The difference between coherence and adherence is that adherence is when a liquid sticks to an object ( different things stick together) and coherence is when a liquid sticks to a liquid ( same things stick together) :D
What is the difference between unity and coherence?
the difference between coherence and unity is nothing
What is the relation between wave length and the color of light?
Different colors have different wavelengths
Differences between the groups in the EM spectrum?
Only their wavelengths are different.
What purpose do linking expressions serve?
Linking expressions serve to connect ideas, show relationships between different pieces of information, and guide the reader or listener through a text or conversation. They help create coherence and coherence in communication by providing smooth transitions between different points or arguments.
What is the relationship between electromagnetic spectrum and sight?
Different wavelengths on the spectrum are seen as different colors within the visible light section of the spectrum.

What is difference between coherency and consistency?
Coherence insures that writes to a particular location will be seen in order. • Consistency insures that writes to different locations will be seen in an order that makes sens
How long are X-ray wavelengths compared with ultraviolet wavelengths?
Ultraviolet photons have wavelengths below 400nm. X-ray photons have wavelengths between 0.01nm - 10nm. Photons with wavelengths smaller than xrays' are called gamma rays.
