The speed of an electromagnetic wave in a material medium of permeability `mu` and permittivity `epsilon` is

Options

A. `(1)/(muepsilon)`
B. `(1)/(2muepsilon)`
C. `(1)/(sqrt(muepsilon))`
D. `(1)/(sqrt(2muepsilon))`

Answer

C

Explanation

If the absolute magnetic permeability of a medium is `mu` and its absolute electric permittivity is `epsilon`, the speed of electromagnetic wave in that medium,
`v=(1)/(sqrt(muepsilon))`
