👉 Light particles, often referred to as photons, are fundamental units of electromagnetic radiation. These particles are massless and travel at the speed of light in a vacuum, approximately 299,792 kilometers per second. They are the primary carriers of light and other forms of electromagnetic radiation, such as radio waves and X-rays. Light particles are created when energy is emitted or absorbed by atoms or molecules, resulting in transitions between different energy levels. These transitions can occur spontaneously or be induced by external factors like heat or electric fields. Photons interact with matter through various processes, including absorption, reflection, refraction, and scattering, which are crucial for phenomena like vision, photosynthesis, and the functioning of optical devices. Despite their lack of mass, light particles exhibit both wave-like and particle-like properties, a concept known as wave-particle duality, which is a cornerstone of quantum mechanics.
