👉 Light particles, often referred to as photons or light quanta, are fundamental entities that exhibit both wave-like and particle-like properties. In the context of quantum mechanics, these particles are the smallest units of light and electromagnetic radiation. They are indicated by the term "light particles" to emphasize their discrete nature and their role in various physical phenomena, such as illumination, photosynthesis, and communication. Light particles travel at the speed of light in a vacuum, approximately 299,792 kilometers per second, and their behavior can be described using quantum theory, which explains how they interact with matter and other light particles. This concept is crucial in understanding processes like reflection, refraction, and the photoelectric effect, where light energy is absorbed by atoms or molecules, leading to the emission of electrons or other particles.
