7. [K-1]A single-slit diffraction pattern is produced when monochromatic light illuminates a narrow slit, as in Figure I below. A second identical slit is then placed between the source and the first slit, as shown in Figure II. What will happen to the maxima?

[K-1]The diagram to the right shows a single slit with lines marking the direction to P to a point P in the diffraction pattern generated. X and Y are the edges of the slit. x The possible value for the path difference, PY - PX, that places P at the first intensity minimum adjacent to the central maximum is: a. 22 c. 2/2 b. 2 d. 2/4
