A) \[I=4{{I}_{0}}{{\cos }^{2}}(\phi /2)\]
B) \[\Rightarrow \]
C) \[\phi =2\pi /3\]
D) \[\Delta x\times (2\pi /\lambda )=2\pi /3\]
Correct Answer: B
Solution :
Let \[f(x)={{x}^{2}}\] \[\therefore \] \[f(1)=f(-1)=1\] Also, f(x) is continuous and differentiable in the given interval.You need to login to perform this action.
