👉 Coordination between light particles, often referred to as photons, involves the fundamental interactions that govern how these massless, electrically neutral particles behave and influence their surroundings. Photons, which are the quanta of electromagnetic radiation, can be thought of as particles of light. When light interacts with matter, such as atoms or molecules, it can transfer energy and momentum through processes like absorption, emission, and scattering. These interactions are coordinated by the electromagnetic field, which mediates the force between charged particles and photons. In a coherent state, such as in laser light, photons maintain a consistent phase relationship, leading to synchronized behavior across the light wave. This coordination is crucial for phenomena like interference and diffraction, where the wave-like properties of light become evident. At a more microscopic level, the emission and absorption of photons by atoms follow specific quantum rules, ensuring that transitions between energy levels are probabilistic yet governed by precise selection criteria, thus maintaining the overall coherence and predictability of light-matter interactions.
