I did not understand what is meant by the center of the pattern here.
a) I have ## \delta \theta_{hw} = \frac { \lambda }{Nd \cos{\theta }} ##
For central maximum ## \theta = 0##, so central line has less width than other line. So, the central line is towards left. But, how to decide center of pattern?
b) Since angular half – width is proportional to ## \lambda ## , for less ## \lambda ## , the half – widths of the line will be less.
