In free space electric field component \(E\left( {z,\;t} \right) = {10^3}\sin \left( {\omega t - {\beta _z}} \right){a_y}\left( {V\;/\;m} \right)\). If the operating frequency is 95.5 MHz, which of the following conclusions is / are correct?
1
\(H\left( {z,\;t} \right) = \frac{{ - {{10}^3}}}{{120\pi }}\sin \left( {\omega t - {\beta _z}} \right){a_x}\left( {A\;/\;m} \right)\)
2
\(H\left( {z,\;t} \right) = \frac{{{{10}^3}}}{{120\pi }}\sin \left( {\omega t - {\beta _z}} \right){a_x}\left( {A\;/\;m} \right)\)
