A) zero
B) 3
C) infinite
D) 5
Correct Answer: B
Solution :
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 maxim as, \[0,\pm 1\] i.e. 3You need to login to perform this action.
