Theoretically the speed of light c through vacuum is expressed as c = 1 /√(εoμo) , εo and μo are the electric permittivity and magnetic permeability of free space (vacuum). Therefore, for a medium with dielectric constant κκ, the speed of light (v) should be expressed as Group of answer choices v = κκ /√(εoμo) v = 1 /√(κκ εoμo) v = √(εoμo) / κκ v = 1 /κκ √( εoμo)
