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 are the two coherent sources obtained in the young double slit experiment?
By splitting what is originally a single beam of light.
Why two distant flash lights do not produce interference fringes?
to produce interference pattern the sources should be coherent but two independent sources cannot produce such pattern. hence they won't produce interference fringes
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 distant flash lights will not produce an interference pattern?
Yes, all waves create interference (such as light waves)

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 will light from two closely spaced stars not produce a steady interference pattern at the earth's surface?
For a steady interference pattern, the two sources of light must be monochromatic and coherent.The light coming from any star contains many wavelengths. Hence, it is not monochromatic.Also, the light is from two different sources. So, the two sources will not be coherent.Because of these reasons, the stars will not produce a stable interference pattern.

Yes, all waves create interference (such as light waves)
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.
What is the difference between diffraction and diffusion?
Diffraction is the spreading of waves that pass through a narrow opening or move past an obstacle ,whereas, interference is the phenomenon of redistribution of light in a medium as a result of light waves from two coherent 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.
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.
Why do you use biprism in fresnel biprism experiment?
To make two coherent source for interference .Biprism make two sources.
