👉 Light particles, also known as photons, are fundamental entities that constitute electromagnetic radiation. They are massless, point-like particles that travel at the speed of light in a vacuum, approximately 299,792 kilometers per second. These particles are produced through various processes, including the decay of atomic nuclei, when atoms or molecules emit energy in the form of light, and during interactions with high-energy photons or electrons. In stars, for instance, light particles are generated through nuclear fusion reactions, where hydrogen atoms combine to form helium, releasing vast amounts of energy in the form of photons. Additionally, light particles can be produced artificially in laboratories using lasers, which emit coherent beams of photons, and in particle accelerators, where high-energy collisions between particles generate a spectrum of light particles. These particles are crucial for various scientific and technological applications, from understanding the universe's structure to powering modern communication systems.
