Why is Interference pattern not detected when the two coherent sources are far apart?

Asked by Topperlearning User | 4th Jun, 2014, 01:23: PM

Expert Answer:

The fringe width in interference pattern is inversely proportional to the separation between the coherent sources (D/d).When the distance d between the coherent source is large, the fringe width becomes very small. In such a case, the fringes may overlap and the interference pattern may not be observed
