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 Ω
• B. 376.6 Ω
• C. 1883 Ω
• D. 3776 Ω

Answer 1

The correct option is C 1883 Ω

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

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