A plane wave in a non-magnetic medium has \(\vec{E}=20\pi\sin\left(10^{8} t-z\right)\hat a_y \ V/m\). The magnetic field \(\vec H\) in the medium is given by,
1
\(2\sin\left(10^{8}t-2z\right)\hat a_{x}\)
2
\(5\sin\left(10^{8}t-z\right)\hat a_{y}\)
3
\(-0.5\sin\left(10^{8}t-z\right)\hat a_{x}\)
4
\(-2\sin\left(10^{8}t-z\right)\hat a_{y}\)
