Question

How can we define refractive index in terms of frequency of light waves?

Answer 1

$$\begin{gathered} Refractiveindexofmediumisgivenby: \\ \mu =\frac{c}{v} \\ wherevisthevelocityofwaveinthemediumandcisthespeedoflightinair \\ v=f\lambda \\ wherefisthefrequency \\ \mu =\frac{C}{f\lambda } \end{gathered}$$
