👉 Light particles, often referred to as photons, are fundamental quanta of electromagnetic radiation. These particles are incredibly small and massless, yet they carry energy and momentum. Photons are the primary carriers of light and other forms of electromagnetic radiation, such as radio waves and X-rays, enabling phenomena like vision, photosynthesis, and communication. They travel at the speed of light in a vacuum, approximately 299,792 kilometers per second, and their behavior is governed by quantum mechanics. Photons can exhibit both wave-like and particle-like properties, a duality that is central to quantum theory. This unique nature makes them essential in various scientific and technological applications, from solar energy conversion to medical imaging and quantum computing.
