Describe an experimental set up to Young's double slit experiment.

Fig. shows an experimental set up simillar to Young's double slit experiment to observe interference of light. Here SS_(2) - SS_(1) = lambda//4 . Write down the conditions of (i) Contstructive interference (ii) Destructive interference at any point P in terms of path diff. (S_(2)P - S_(1)P) . Does the central fringe observed in the above set up lie above or below O ? Give reason.

In Young's double slit experimental set up, it the wavelength alone is doubled the band width beta becomes,
