Relationship between `epsilon_(0)`, `mu_(0)`, and velocity of light

The dimensions of epsilon_(0)mu_(0) are

Relationship between frequency (V) wavelength (lambda) and velocity of light (c) is

In a certain medium the relationship between the group and phase velocities of an electromagnetic wave has the form uv = c^(2) , where c is the velocity of light in vaccume. Find the dependence of permittivity of that medium on wave frequency, epsilon(omega) .

In terms of potential difference C , electric current I , permittivity epsilon_(0) , permeability mu_(0) and speed of light c , the dimensionally correct equation (s) is (are)
