👉 Light particles, also known as photons, are fundamental components of electromagnetic radiation and are considered the smallest discrete packets of energy. These particles are massless and travel at the speed of light in a vacuum, exhibiting both wave-like and particle-like properties—a concept central to quantum mechanics. Photons are emitted or absorbed during various physical processes, such as when electrons transition between energy levels in atoms or molecules. They carry energy and momentum, making them crucial in phenomena like photosynthesis, where they facilitate the transfer of energy from sunlight to plants, and in the operation of technologies like lasers and fiber optics. Understanding light particles is essential for grasping how light interacts with matter and underpins many areas of physics and engineering.
