👉 Light particles, often referred to as photons, are fundamental entities that constitute light. These particles are massless and travel at the speed of light in a vacuum, approximately 299,792 kilometers per second. Unlike matter particles, photons do not have an internal structure; they are pure energy. They exist as discrete packets of energy, which means they can be emitted or absorbed in specific amounts, a principle known as quantization. This property is crucial in phenomena like the photoelectric effect and quantum entanglement. Light particles interact with matter through processes such as reflection, refraction, and absorption, but their primary nature is that of pure energy transfer, making them essential in understanding light's behavior and its applications in physics, from optics to quantum mechanics.
