I found the intrinsic impedance but I'm not sure which equation to choose?(adsbygoogle = window.adsbygoogle || []).push({});

Any suggestion? Thanks

Express both E and H as functions of time for a 30-Mhz uniform plane wave propagating in the positive z direction in a lossless medium having [tex]\varepsilon[/tex] = 20pR/m and [tex]\mu[/tex] = 5 uH/m. E has only an x component and it reaches a positive maximum amplitude of 800 v/m at z = 0.4m when t = 6ns.
