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