![The electric field of a plane wave propagating in a nonmagnetic material is given by:
\[
E = \begin{bmatrix}
0 \\
3 \cdot \cos(2 \cdot \pi \cdot 10^7 \cdot t - 0.4 \cdot \pi \cdot x) \\
4 \cdot \cos(2 \cdot \pi \cdot 10^7 \cdot t - 0.4 \cdot \pi \cdot x)
\end{bmatrix} \cdot \frac{V}{m}
\]
Find the following:
(a) The direction of wave propagation.
(b) The phase velocity.
(c) The relative permittivity of the material.
(d) The intrinsic impedance.
(e) The magnetic field phasor \(\mathbf{H(z)}\).
(f) The instantaneous magnetic field \(\mathbf{H(z,t)}\).](https://content.bartleby.com/qna-images/question/4bdca33e-fe41-4c4f-b2f7-f887541be3fa/108d0a94-2148-4c09-a81f-a3add4f750bc/dl7k8i_thumbnail.png)
