👉 Governing-light-particles refers to the fundamental principles and laws that dictate how light, or photons, interacts with matter at a microscopic level. Light particles, or photons, are governed by quantum mechanics and electromagnetism. According to quantum theory, light exists as discrete packets of energy, each carrying an energy proportional to its frequency (E = hν, where E is energy, h is Planck's constant, and ν is frequency). These particles exhibit both wave-like and particle-like properties, a duality central to quantum mechanics. Their behavior, including emission, absorption, reflection, refraction, and interference, is described by Maxwell's equations for electromagnetic waves and the principles of quantum electrodynamics (QED), which explain how light interacts with charged particles like electrons in atoms. This governing framework underpins our understanding of optical phenomena and forms the basis for technologies ranging from lasers to fiber optics.
