Monochromatic sources ensure that the waves produced have a single well-defined frequency, which leads to stable and predictable interference patterns. If the sources have different frequencies, the interference pattern would be more complicated and less predictable.

What is the difference between a monochromatic light and coherent light waves?
Monochromatic light refers to light of a single wavelength, while coherent light waves have a fixed phase relationship with each other, leading to interference patterns. Monochromatic light can consist of multiple coherent light waves as long as they share the same wavelength.
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.
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 are two different sources are not coherent?
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coherent because they present conflicting information, have different perspectives or biases, or rely on inaccurate or outdated data.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 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.
Why are two different sources are not coherent?
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coherent because they present conflicting information, have different perspectives or biases, or rely on inaccurate or outdated data.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.
Why are two independent sources of light used to illuminate the two slits in Young's double slit experiment?
Two independent sources are used to ensure the light waves passing through each slit are coherent. Coherence is necessary for the interference pattern to form. If a single source is used, the split beam may not be coherent, leading to a washed-out interference pattern.
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.
Why do you use biprism in fresnel biprism experiment?
To make two coherent source for interference .Biprism make two sources.
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.
What are the condition for good interference pattern?
Good interference patterns are achieved when the two sources emit coherent waves of the same frequency and amplitude. The sources should be close enough to create interference, but far enough to avoid diffraction effects. Additionally, the waves should have a consistent phase relationship to produce clear and distinct interference fringes.
What is the meaning of two coherent source?
The meaning it carries by saying that a source A and Source B are coherent source means that for a certain place of consideration the light from these sources arrive at the same phase or at such phases whose difference doesn't change over time.
