👉 Light particles, often referred to as photons, are fundamental components of electromagnetic radiation. These particles are massless and exhibit both wave-like and particle-like properties, a concept known as wave-particle duality. Photons carry energy and momentum, with their energy directly proportional to the frequency of the light they represent, as described by Planck's equation (E = hν). They travel at the speed of light in a vacuum, approximately 299,792 kilometers per second, and are essential for various phenomena, including photosynthesis, vision, and communication technologies like fiber optics and lasers. Despite their lack of mass, photons can interact with matter, causing processes such as absorption, reflection, and refraction, which underpin many physical and biological systems.
