A) \[a\sin \theta =\frac{\lambda }{2}\]
B) \[a\cos \theta =\frac{3\lambda }{2}\]
C) \[a\sin \theta =\lambda \]
D) \[a\sin \theta =\frac{3\lambda }{2}\]
Correct Answer: D
Solution :
For nth secondary maxima path difference \[d\sin \theta =(2n+1)\frac{\lambda }{2}\] \[\Rightarrow \]\[a\sin \theta =\frac{3\lambda }{2}\]You need to login to perform this action.
