A) \[0{}^\circ \]
B) \[15{}^\circ \]
C) \[30{}^\circ \]
D) \[60{}^\circ \]
Correct Answer: C
Solution :
For the first minima \[d\sin \theta =\lambda \] \[\Rightarrow \] \[\sin \theta =\frac{\lambda }{d}\,\,\,\,\Rightarrow \]\[\theta ={{\sin }^{-1}}\left( \frac{5000\times {{10}^{-10}}}{0.001\times {{10}^{-3}}} \right)={{30}^{o}}\]You need to login to perform this action.
