## Main Question or Discussion Point

how these two are related to each there? if refractive index is given as a function of angular frequency, how both are related? reflective index= omega*c / k.anyone?

[tex]\frac{d\omega}{dk}[/tex]

Where

[tex] k = \frac{k_0}{n}[/tex]

Where [itex]k_0[/itex] is the free-space wave-vector and [itex]n[/itex] is the refractive index of the medium.
