👉 Light particles, also known as photons, are the fundamental quanta of electromagnetic radiation, including visible light. These particles are incredibly small and massless, exhibiting both wave-like and particle-like properties—a duality that is central to quantum mechanics. Photons are created when energy is emitted or absorbed in discrete packets, which is why they can be thought of as the smallest units of light. Each photon carries a specific amount of energy proportional to the frequency of the light it represents, as described by Planck's equation (E = hν). This means that higher-energy photons, such as those in the ultraviolet or X-ray regions of the spectrum, carry more energy per unit of time compared to lower-energy photons like those in the infrared or visible range. Despite their minuscule size, photons play a crucial role in various natural phenomena and technological applications, from the photoelectric effect that powers solar cells to the intricate processes occurring within atoms and molecules. Their behavior and interactions underpin much of our understanding of light and its effects on matter.
