Optics Question 181
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
Options:
A) 5 W
B) 376.6 W
C) 1883 W
D) 3776 W
Show Answer
Answer:
Correct Answer: C
Solution:
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 $
