Wave-Particle Interactions

Wave-particle interactions occur when particles such as electrons or ions in space or a plasma respond to electromagnetic waves, like radio signals or natural vibrations. These interactions influence how particles gain or lose energy, change direction, or become accelerated. For example, in Earth's magnetosphere, energetic particles can resonate with plasma waves, affecting space weather. Essentially, waves and particles exchange energy and momentum, shaping behaviors in environments like space, astrophysics, and laboratory plasmas—fundamentally linking wave motions to particle dynamics across various settings.
