👉 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, which have mass and can interact through various forces like gravity, electromagnetism, and strong/weak nuclear forces, light particles are purely energy carriers. They exist as quanta of electromagnetic radiation, meaning they come in discrete packets of energy, known as photons. Each photon carries a specific amount of energy proportional to its frequency, described by Planck's equation (E = hf). This concept is crucial in understanding phenomena like the photoelectric effect and quantum optics. Light particles are essential in many areas of physics and technology, from solar energy conversion to fiber optics and laser operations.
