A) \[\frac{\lambda }{2}(n-l)\]
B) \[\lambda (n+l)\]
C) \[\frac{\lambda }{2}(n+l)\]
D) \[\lambda (n-l)\]
Correct Answer: B
Solution :
For maxima \[2\pi \,n=\frac{2\pi }{\lambda }(XO)-2\pi \,l\] or \[\frac{2\pi }{\lambda }(XO)=2\pi (n+l)\] or \[(XO)=\lambda (n+l)\]You need to login to perform this action.
