(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

For a plane em wave in vacuum can write [tex]k=\frac{w}{c}[/tex]

what is the equivalent relation in a dielectric?

2. Relevant equations

[tex]\frac{1}{c^2}={\epsilon}{\mu}[/tex]

3. The attempt at a solution

[tex] k=\sqrt{{\epsilon_{r}}\epsilon\mu}.w[/tex]

This right?
