(D. R. Nicholson ~ 1.3) In the deduction of the electron plasma frequency, suppose the ions are not infinitely massive, but have a mass mi
and can move. Modify the discussion to show that the coupled oscillation of the electron and ion " slabs " is made with the total plasma frequency
\((\omega_p^2 = \omega_{pe}^2 + \omega_{pi}^2)\).
