WebThis is known as the dispersion relation. For example, light waves in a vacuum have the dispersion relation != ck, and sound waves also have a linear dispersion relation. In … called the Bohm–Gross dispersion relation. If the spatial scale is large compared to the Debye length, the oscillations are only weakly modified by the pressure term, but at small scales the pressure term dominates and the waves become dispersionless with a speed of ,. See more Plasma oscillations, also known as Langmuir waves (after Irving Langmuir), are rapid oscillations of the electron density in conducting media such as plasmas or metals in the ultraviolet region. The oscillations can be … See more Consider an electrically neutral plasma in equilibrium, consisting of a gas of positively charged ions and negatively charged See more • Longair, Malcolm S.
