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.
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 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.
What are the two main sources of light energy?
The two main sources of light energy are natural light from the sun and artificial light from sources like light bulbs and lamps. Both sources produce electromagnetic radiation that our eyes perceive as light.

What is the difference between a monochromatic light and coherent light waves?
The term "mono" refers to a singular object or subject. The term "chrome" refers to colors. The term "monochrome" is a reference to a single color. ie., if two lights are monochromatic that means they have same wavelength. If two waves are monochromatic (having the same wavelength) and are of the same phase, these two waves are defined as coherent waves. Sources generating such waves are known as coherent 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.
Why two distant flash lights will not produce an interference pattern?
Two distant flashlights will not produce an interference pattern because the distance between them is too large for the light waves to interact and interfere with each other. The interference is only noticeable when the distance between the sources is comparable to the wavelength of the light.
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.
Describe fresnel biprism?
A fresnel biprism is a triangular right prism with a highly obtuse angle in cross-section. The obtuse angle is near 180 degrees. The typical use of such a prism is to produce two coherent "virtual" light sources from one real point source. These virtual sources can be used to demonstrate interference.
How are the two coherent sources obtained in the young double slit experiment?
In the Young's double slit experiment, two coherent sources are typically achieved by splitting a single light source using a thin barrier with two closely spaced slits. When light passes through these slits, it creates waves that interact with each other, resulting in an interference pattern on a screen placed behind the slits. This setup ensures that the light waves from the two slits maintain a constant phase relationship, leading to the formation of interference fringes.
