A) \[\frac{2\pi }{\lambda }({{L}_{1}}-{{L}_{2}})\]
B) \[\frac{2\pi }{\lambda }({{\mu }_{1}}{{L}_{1}}-{{\mu }_{2}}{{L}_{2}})\]
C) \[\frac{2\pi }{\lambda }({{\mu }_{2}}{{L}_{1}}-{{\mu }_{1}}{{L}_{2}})\]
D) \[\frac{2\pi }{\lambda }\left[ \frac{{{L}_{1}}}{{{\mu }_{1}}}-\frac{{{L}_{2}}}{{{\mu }_{2}}} \right]\]
Correct Answer: B
