WebThe imaginary part of the index of refraction, i.e. κ, quantifies the dissipation of light through a medium. However, if one wants to quantify the dissipation due to nonretarded electric fields alone, the quantity that quantifies this is not ϵ b but Im 1 ϵ, where ϵ is the total dielectric function. WebRefractive index. The speed of light is determined by the medium (material) through which the light is travelling. Light travels faster in a vacuum than it does in any other medium. thorne supplements testing
