7. Two incoherent line sources S and S2 each emitting monochromatic light of wavelength à are placed symmetrically in front of an opaque screen A containing two symmetrically positioned slits. In front of screen A another white screen B is placed as shown schematically in the S1 figure. Distance between the sources is l and that between the slits is d. 1. Distance between the sources and the screen A as well as that between screens A and B is D. The distance D is much larger than the distances S2 1 and d. For what values of the distance l between the sources, no stationary interference pattern will be observed on the screen B? Ans: l= (2n+1)aD 2d in=0,1,2..
