Symbol: | |||

Definition: | the oscillation frequency at which a plasma, locally disturbed by an excess or depletion of electrons, reverts to its macroscopic state of neutral equilibrium, supposing that the ions remain fixed in position
NOTE – The plasma frequency $f}_{p}=\frac{e}{2\pi}\sqrt{\frac{{n}_{\text{e}}}{m{\epsilon}_{0}}$

$f}_{p}=\frac{e}{2\pi}\sqrt{\frac{{n}_{\text{e}}}{m{\epsilon}_{0}}$

where *e* is the electron charge, *m* is the electron mass, *n*_{e} is the electron density, *ε*_{0} is the electric constant.
