What are coherent sources ?

A : Light added to light can produce darkness. R : The destructive interference of two coherent light sources may give dark fringe.

The intensity ratio of two coherent sources of light is p. They are interfering in some region and produce interference patten. Then the fringe visibility is

Consider the following statement A and B and identify the correct answer A) In the case of narrow source of light coherent sources are obtained by the division of wave front B) Diffraction is due to interference of light from secondary sources of the same wave front whereas interference is due to superposition of two waves derived from the same source.

When two coherent sources interact with each other, there will be production of alternate bright and dark fringes on the screen . Young's double-slit experiment domonstrates the idea of making two coherent sources. For better visibility, one has to choose proper amplitude for the sources. The phenomena is good enough to satisfy the conservation of energy principle. The pattern formed in YDSE is of uniform thickness and is nicely placed on a long distance screen. Law of convervation of energy is satisfied because

Young's double-slit experiment domonstrates the idea of making two coherent sources. For better visibility, one has to choose proper amplitude for the sources. The phenomena is good enough to satisfy the conservation of energy principle. The pattern formed in YDSE is of uniform thickness and is nicely placed on a long distance screen. The best combination of independent sources to produce sustained pattern among the following is Y_(1) = a sin omega t Y_(2) = a cos omega t Y_(3) = a sin (omega t + (pi)/(4)) Y_(4) = 2a sin (omega t + pi)

The phenomenon of diffraction can be treated as interference phenomenon if the number of coherent sources is

In Young's double slit experiment, the ratio of maximum and minimum intensities in the fringe system is 9:1 the ratio of amplitudes of coherent sources is

Why coherent sources are required to create interference of light ? Explain how Fresnel biprism is used to obtain two coherent sources of light.
