    For a medium with permittivity\[\varepsilon \]and permeability\[\mu ,\]the velocity of light is given by

    A)  \[\sqrt{\mu /\varepsilon }\]           

    B) \[\sqrt{\mu \varepsilon }\]

    C)  \[1/\sqrt{\varepsilon /\mu }\]         

    D)  \[\sqrt{\varepsilon /\mu }\]

    Correct Answer: C

    Solution :

    Velocity of light \[c=1/\sqrt{\mu \varepsilon }\], where \[\mu \] is permeability and e is permittivity of the medium.
