Q. 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) $3776\ \Omega$
Explanation
(c) Wave impedance $Z = \sqrt{\frac{\mu_{r}}{\varepsilon_{r}}} \times \sqrt{\frac{\mu_{0}}{\varepsilon_{0}}}$
$= \sqrt{\frac{50}{2}} \times 376.6 = 1883\Omega$
