👉 Light particles, often referred to as photons, are fundamental entities that constitute electromagnetic radiation. These particles are incredibly small and massless, existing as packets of energy rather than solid matter. Photons travel at the speed of light in a vacuum, approximately 299,792 kilometers per second, and they carry energy proportional to their frequency—a relationship described by Planck's equation. This means that higher-energy light, such as gamma rays, can have more significant impacts on matter, while lower-energy light, like visible light, interacts differently with materials. Photons are the primary carriers of electromagnetic forces, enabling phenomena such as reflection, refraction, and absorption, which underpin many natural processes and technological applications, from photosynthesis in plants to the functioning of solar panels. Despite their minuscule size, photons play a crucial role in our understanding of the universe, from the behavior of atoms to the structure of stars.
