(D. R. Nicholson ~ 1.3) In the deduction of the electron plasma frequency, suppose the ions are not infinitely massive, but have a mass $m_i$ and can move. Modify the discussion to show that the coupled oscillation of the electron and ion $\textquotedblleft$ slabs $\textquotedblright$ is made with the total plasma frequency

\((\omega_p^2 = \omega_{pe}^2 + \omega_{pi}^2)\).
