Plasma Oscillations – “Langmuir Wave” approximation derivation

In a previous article we established an approximate estimate for the frequency of oscillations in a “cold plasma” because of small disturbances in the arrangement of the electrons and ions. In this article we will establish a much better model for oscillations in a plasma, which takes into consideration the fact that Plasmas tend to be […]

Cold Plasma Oscillations – Frequency Derivation

At low temperatures it is not a bad model to take a plasma as a collection of ions and electrons, with the ions always stationary, and the electrons oscillating, due to the force upon them due to the opposing charges of the electrons and ions. For this derivation we will assume that the ions ans […]
