What is meant by coherent sources of light? Assertion :Only coherent light sources produce sustained interference. Reason: Coherent light sources emit lights of same wavelength and with a constant phase difference.
In Young's double-slit experiment, the separation between two coherent sources S1 and S2 is d and the distance between the source and screen is D. In the interference pattern, it is found that exactly in front of one slit, there occurs a minimum.
Coherent and Incoherent Addition of waves Suppose there is a surface of the water and you take a needle and touch the surface of the water. What will happen? Yes, ripples are formed. Now if you take two needles and you touch the surface of the water with the needles. What do you think will happen? You will see a pattern. That pattern is the interference pattern. When you touch both the needles at the surface of the water at the same time, both the needles are in the same phase. Needle 1 will ...
(a) What are coherent sources of light? State two conditions for two light sources to be coherent. (b) Derive a mathematical expression for the width of interference fringes obtained in Young's double slit experiment with the help of a suitable diagram. (c) If s is the size of the source and b its distance from the plane of the two slits, what should be the criterion for the interference fringes to be seen? OR (a) In Young's double slit experiment, describe briefty how bright and dark ...
7 C's of communication - concise, clear, correct, concrete, complete, courteous and coherent together form the principles of business communication. Let us learn in more detail about 7 C's of communication.
Assertion :Only coherent light sources produce sustained interference. Reason: Coherent light sources emit lights of same wavelength and with a constant phase difference.
Coherent Sources: Two sources giving light waves of same frequency and zero or constant initial phase are called coherent sources.
