The electric field in a plane electromagnetic wave is given by
\(\text{E}_\text{z}\,=\,60\, \text{cos}\left(5\text{x}\,+\,1.5 \times 10^9 \text{t}\right)\,\text{V/m}\).
Then the expression for the corresponding magnetic field is (here subscripts denote the direction of the field):
\(\text{E}_\text{z}\,=\,60\, \text{cos}\left(5\text{x}\,+\,1.5 \times 10^9 \text{t}\right)\,\text{V/m}\).
