A) \[\cos \delta \]
B) \[\cos \left( \frac{\delta }{2} \right)\]
C) \[{{\cos }^{2}}\left( \frac{\delta }{2} \right)\]
D) \[{{\cos }^{2}}\delta \]
Correct Answer: C
Solution :
Maximum intensity, \[I=4{{I}_{0}}{{\cos }^{2}}\left( \frac{\delta }{2} \right)\] \[\Rightarrow \] \[I\propto {{\cos }^{2}}\left( \frac{\delta }{2} \right)\]You need to login to perform this action.
