A) zero
B) 3
C) infinite
D) 5
Correct Answer: B
Solution :
[b] As\[\sin \theta =\frac{n\lambda }{d}\]and\[\sin \theta \]cannot be\[1\] \[\therefore \,\,\,1=\frac{n\lambda }{1.8\lambda }\] or \[n=1.8\] Hence maximum number of possible interference maximas, 0, \[~\pm 1\] i.e. 3You need to login to perform this action.
