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.
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 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.
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coherent because they present conflicting information, have different perspectives or biases, or rely on inaccurate or outdated data.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.

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.

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coherent because they present conflicting information, have different perspectives or biases, or rely on inaccurate or outdated data.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 coherent sources are required?
Coherent sources are required in applications like interferometry because they have a constant phase relationship between each other, allowing for constructive and destructive interference patterns to be observed. This coherence ensures that the waves maintain a stable relationship in time and space, leading to the formation of clear interference patterns. Without coherent sources, it would be challenging to achieve the desired interference effects.
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.
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.
Can coherent sources produce interference explain?
Yes, coherent sources can produce interference when the waves emitted from the sources have a constant phase difference and match in frequency and wavelength. This results in the waves either reinforcing (constructive interference) or canceling out (destructive interference) each other, leading to a pattern of alternate bright and dark areas.
What is the formula for fringe width?
Fringe width (for dark and bright bands): D * wavelength / d where, D = distance between screen and coherent sources (metres), wavelength = wavelength of light used is experiment (nanometres), d = distance between the 2 coherent sources (millimetres).
