WebDec 7, 2015 · 2.Coherent Sources of light are the sources which emit light waves of same frequency, same wavelength and have a constant initial phase difference. 3 .Coherent source of light can be obtained by deriving two sources from a primary (or initial) source by (i)division of wavefront (ii)division of amplitude 4. WebLet's calculate the expression for the intensity of interfering waves due to coherent sources. The expression turns out to be I =4 Io cos^2 (phi/2). Created by Mahesh Shenoy. Sort by: …

WebApr 23, 2024 · Reason : In YDSE path difference between the superposing waves can not be more than the distance between the slits. Answer b Q.9. Assertion : Interference pattern is made by using yellow light instead of red light, the fringes becomes narrower. Reason : In YDSE, fringe width is given by β=λD/d Answer a Q.10. WebYoung's Double-slit experiment is a simple demonstration of the wave nature of light. It experimentally verifies that just like waves interfere, light also interferes and forms interference fringes. The setup of Young's double-slit experiment consists of two coherent sources (in form of slits) separated by a small distance 'd'. cummins 15 liter natural gas
