Ion-acoustic waves
WebThe ion-acoustic wave is one of the more easily observed waves in the plasma environments of comets. For example, ion-acoustic waves in the frequency range of 1.0–1.5 kHz were observed by the ICE spacecraft sent to observe the comet Giacobini-Zinner [ 9 , Figure 3]. In plasma physics, an ion acoustic wave is one type of longitudinal oscillation of the ions and electrons in a plasma, much like acoustic waves traveling in neutral gas. However, because the waves propagate through positively charged ions, ion acoustic waves can interact with their electromagnetic fields, as well … Meer weergeven We derive the ion acoustic wave dispersion relation for a linearized fluid description of a plasma with electrons and $${\textstyle N}$$ ion species. We write each quantity as Each species Meer weergeven • Waves in plasmas • Sound • Alfvén wave • Magnetosonic wave • List of plasma (physics) articles Meer weergeven The general dispersion relation given above for ion acoustic waves can be put in the form of an order-N polynomial (for N ion species) in $${\displaystyle u^{2}}$$. All of the … Meer weergeven Ion acoustic waves are damped both by Coulomb collisions and collisionless Landau damping.
