B) \[\frac{1}{\sqrt{{{\mu }_{0}}{{\varepsilon }_{0}}}}\]
C) \[\sqrt{{{\mu }_{0}}{{\varepsilon }_{0}}}\]
D) \[\frac{1}{{{\mu }_{0}}{{\varepsilon }_{0}}}\]
Correct Answer: B
Solution :
The electromagnetic waves travel with the speed of light in vacuum and it is given as \[c=\frac{1}{\sqrt{{{\mu }_{0}}{{\varepsilon }_{0}}}}\]
