A radio wave's electric field is given by the expression $\vec{E}=E \sin (k z-\omega t) \times(\hat{\imath}+\hat{\jmath}) \cdot(\mathrm{a})$ Find the peak electric field. (b) Give a unit vector in the direction of the magnetic field at a place and time where $\sin (k z-\omega t)$ is positive.
A plane electromagnetic wave traveling in the y-direction through vacuum is given by E(x, y, z, t) = E0e^(i(ky - Ιωt)) Determine an expression for the corresponding magnetic field of the electromagnetic wave. Draw a diagram showing E0, B0, and k, the propagation vector.

The electric field of a certain plane electromagnetic wave is given by $E_{x}=0 ; E_{y}=0 ; E_{z}=(2.0 \mathrm{~V} / \mathrm{m}) \cos [(\pi \times$ $\left.\left.10^{15} \mathrm{~s}^{-1}\right)(t-x / c)\right]$, with $c=3.0 \times 10^{8} \mathrm{~m} / \mathrm{s}$. The wave is propagating in the positive $x$ direction. Write expressions for the components of the magnetic field of the wave.
