Question

If ${{\rm{\varepsilon }}_0}{\rm{\;and\;}}{{\rm{\mu }}_0}$ are the electric permittivity and magnetic permeability of free space and ${\rm{\varepsilon \;and\;\mu }}$ are the corresponding quantities in the medium, the index of refraction of the medium in terms of above parameter is

Accepted Answer

${\left( {\frac{{{m{\varepsilon \mu }}}}{{{{m{\varepsilon }}_0}{{m{\mu }}_0}}}\begin{array}{*{20}{c}} {m{\;}}\ {m{\;}} \end{array}} ight)^{1/2}}$

Answer

$\frac{{{\rm{\varepsilon \mu }}}}{{{{\rm{\varepsilon }}_0}{{\rm{\mu }}_0}}}$

Answer

$\left( {\frac{{{{\rm{\varepsilon }}_0}{{\rm{\mu }}_0}}}{{{\rm{\varepsilon \mu }}}}} \right)$

Answer

${\left( {\frac{{{{\rm{\varepsilon }}_0}{{\rm{\mu }}_0}}}{{{\rm{\varepsilon \mu }}}}} \right)^{1/2}}{\rm{\;}}$
