👉 Light particles, often referred to as photons or light rays, are fundamental components of electromagnetic radiation. These particles are massless and travel at the speed of light in a vacuum, approximately 299,792 kilometers per second. Light particles exhibit both wave-like and particle-like properties, a concept known as wave-particle duality. In their particle form, light carries discrete packets of energy, quantified by Planck's constant, which is crucial for explaining phenomena like the photoelectric effect. These particles can be emitted or absorbed by matter, influencing chemical reactions and physical processes. In a broader context, light particles are essential in various applications, from solar energy conversion to medical imaging, where their interaction with matter provides critical information about the environment and biological systems.
