Two sources may not be coherent because they present conflicting information, have different perspectives or biases, or rely on inaccurate or outdated data. Differences in research methodologies, sources of data, or interpretations may also contribute to lack of coherence between sources.

How do you produce two coherent sources of light?
To produce two coherent sources of light, you can use a laser to create a beam of light with a single frequency and direction. By splitting the laser beam into two using a beamsplitter, you can then generate two coherent sources of light that have the same frequency and phase relationship.
What are coherent sources Give example.?
Coherent sources are sources of waves that have a constant phase difference between them. An example of coherent sources is two identical lasers emitting light waves with the same frequency and wavelength.
Why are two independent sources of light used to illuminate the two slits in Young's double slit experiment?
You have to correct the question as,Why are two independent sources of light not used to illuminate the two slits in Young's double slit experiment?We need coherent sources. But two independent sources would emit waves with varying phase difference which makes waves non coherent.
How two coherent sources are realized in fresnel biprism?
In a Fresnel biprism setup, two coherent sources are realized by using a single source that is split into two coherent beams by the biprism. The two beams then interfere with each other to create an interference pattern. This interference pattern contains information about the phase difference between the two beams, allowing for interference effects to be observed.
What are the conditions two light sources to be coherent?
Two light sources are considered coherent if they have a constant phase difference between them and the same frequency. This allows for constructive interference to occur and produce a stable interference pattern. Additionally, the light sources should have similar polarization and be from the same spectral line.

Why two independent sources cannot behave as a coherent sources?
Light is emitted due to the de-excitaton of electrons from higher orbits of the various atoms of the light source.The de-excitation can also be to different levels in different atoms resulting in emission of different wavelengths.A light source will have numerous atoms in it.When you take two light sources it is not possible for all the atoms to get de-excited to the same shell at the same time(causing phase difference) that is why two independent sources cannot be coherent.
How are two coherent sources formed by Fresnel's bi-prism?
Two coherent sourses are produced with the bi-prism by the phenomenon of refraction through the refracting surfaces.

To make two coherent source for interference .Biprism make two sources.
How many bright fringes will be seen in the interference pattern created by two coherent light sources?
The number of bright fringes in an interference pattern created by two coherent light sources is determined by the formula: ( N fracd cdot lambdaD 1 ), where ( N ) is the number of bright fringes, ( d ) is the distance between the two sources, ( lambda ) is the wavelength of the light, and ( D ) is the distance from the sources to the screen.
Why ordinary light is not coherent?
Ordinary light is emitted from various sources with different phases and wavelengths, leading to random and constantly changing interference patterns. This lack of a fixed phase relationship between light waves prevents ordinary light from being coherent. Coherent light sources, like lasers, have a single wavelength and phase, allowing for stable interference patterns.
What are examples of coherent sources?
Examples of coherent sources include lasers, superluminescent diodes, and optical fibers. These sources produce light waves that are in phase with each other, leading to interference patterns and constructive interference.
What is the definition of coherent sources?
Coherent sources are those that radiate waves with same phase or constant phase difference. They're very much essential for producing Fresnel's type of diffraction.
