A) \[24V\,{{m}^{-1}}\]
B) \[10V\,{{m}^{-1}}\]
C) \[30V\,{{m}^{-1}}\]
D) \[6V\,{{m}^{-1}}\]
Correct Answer: A
Solution :
\[{{E}_{ot}}\] and \[{{E}_{oi}}\]be the perpendicular components of the electric field for transmitted and incident waves respectively. \[\frac{{{E}_{ot}}}{{{E}_{oi}}}=\frac{2{{\mu }_{1}}}{{{\mu }_{1}}+{{\mu }_{2}}}=\frac{2(1)}{1+1.5}=\frac{4}{5}\] \[\Rightarrow \]\[{{E}_{ot}}=30\times \frac{4}{5}=24V\,{{m}^{-1}}\]
