In the standard Young's double slit experiment, the intensity on the screen at a point distant 1.25 fringe widths from the central maximum is (assuming slits to be identical)

In Young's double slit experiment, the intensity on the screen at a point where path difference is lambda is K. What will be the intensity at the point where path difference is lambda//4 ?

In Young's double slit experiment, the intensity on the screen at a pont where path difference lamda is K. what will be the intensity at the point where the path difference is lamda/4 ?
