A) \[\sqrt{{{\mu }_{0}}{{\varepsilon }_{0}}}\]
B) \[\sqrt{\frac{{{\mu }_{0}}}{{{\varepsilon }_{0}}}}\]
C) \[\sqrt{\frac{1}{{{\mu }_{0}}{{\varepsilon }_{0}}}}\]
D) \[\sqrt{\frac{{{\varepsilon }_{0}}}{{{\mu }_{0}}}}\]
Correct Answer: C
Solution :
The speed of light in vacuum is given by\[\sqrt{\frac{1}{{{\mu }_{0}}{{\varepsilon }_{0}}}}.\]where \[{{\mu }_{0}}\]is permeability and \[{{\varepsilon }_{0}}\] is permittivity of free space.
