The phase difference between two light waves emerging from the slits of Young’s experiment is  radians. Will the central fringe be bright or dark?

Expert Answer:

The wave from the slits travel the same distance to arrive at central fringe. Therefore, there is no path difference between the waves reaching here. But if there is an initial phase difference of  radians between the two waves, the central fringe will be dark.
