If an electromagnetic wave is propagation in a medium with permeability 

\mathrm{\varepsilon }

and permittivity

\mathrm{\mu }

, then

\sqrt {\frac{\mathrm{\mu }}{\mathrm{\varepsilon }}}

is the

View answer and explanation

Correct option: A

Intrinsic impedance of the medium

The correct answer is A (Intrinsic impedance of the medium) because

\sqrt {\frac{{\rm{{\mu }}}}{{\rm{{\varepsilon }}}}}

represents the intrinsic impedance of a medium.
