👉 Light particles, often referred to as photons or light quanta, are fundamental entities that constitute electromagnetic radiation and other forms of light. These particles are massless and exhibit both wave-like and particle-like properties, a concept encapsulated by quantum mechanics. According to the most widely accepted theory, light is composed of discrete packets of energy, or photons, which carry energy proportional to their frequency (E = hν, where E is energy, h is Planck's constant, and ν is frequency). This dual nature—being both particles and waves—explains phenomena such as the photoelectric effect, where light can eject electrons from a material, and interference patterns in double-slit experiments. Light particles are central to understanding how energy is transferred and transformed in the universe, from the sun's rays reaching Earth to the intricate workings of electronic devices that rely on light for communication and computation.
