A) \[2({{\ell }_{1}}-{{\ell }_{1}})\]
B) \[\frac{1}{2}(2{{\ell }_{1}}-{{\ell }_{2}})\]
C) \[\frac{{{\ell }_{2}}-3{{\ell }_{1}}}{2}\]
D) \[\frac{{{\ell }_{1}}-{{\ell }_{2}}}{2}\]
Correct Answer: C
Solution :
\[{{\ell }_{1}}+x=\lambda /4\] \[{{\ell }_{2}}+x=\frac{3\lambda }{4}\] \[\Rightarrow \]\[x=\frac{{{\ell }_{2}}-3{{\ell }_{1}}}{2}\] Hence, the correction option is [c].You need to login to perform this action.
