A) \[\sqrt{\frac{{{\varepsilon }_{0}}}{{{\mu }_{0}}}}\]
B) \[\sqrt{{{\mu }_{0}}{{\varepsilon }_{0}}}\]
C) \[\sqrt{\frac{1}{\sqrt{{{\mu }_{0}}{{\varepsilon }_{0}}}}}\]
D) \[\sqrt{\frac{{{\mu }_{0}}}{{{\varepsilon }_{0}}}}\]
Correct Answer: C
Solution :
Velocity of electromagnetic radiation is the velocity of light , i.e., \[c=\frac{1}{\sqrt{{{\mu }_{0}}{{\varepsilon }_{0}}}}\] where\[{{\mu }_{0}}\]is the permeability and\[{{\varepsilon }_{0}}\]is the permittivity of free space.
