👉 Light particles, also known as photons, are fundamental entities that make up light and other forms of electromagnetic radiation. These particles are incredibly small and massless, existing as waves of energy rather than matter. They travel at the speed of light in a vacuum, approximately 299,792 kilometers per second, and carry no electric charge. Light particles interact with matter through processes like absorption, emission, and scattering, which underpin phenomena such as photosynthesis, vision, and the transmission of information via fiber optics. Despite their lack of mass, photons exhibit properties of both waves and particles, a duality that is central to quantum mechanics.
