Question

A wave is propagating in a medium of electric dielectric constant 2 and relative magnetic permeability 50. The wave impedance of such a medium is

• A. 5 $\Omega$
• B. 376.6 $\Omega$
• C. 1883 $\Omega$
• D. 3776 $\Omega$

Answer 1

The correct option is C

1883 $\Omega$

Wave impedance $Z=\sqrt{\frac{{\mu }_r}{{ϵ}_r}}\times \sqrt{\frac{{\mu }_0}{{ϵ}_0}}$

$=\sqrt{\frac{50}{2}}\times 376.6=1883\Omega$
