👉 The marketplace of light particles, often referred to as photons or light quanta, is a fundamental concept in quantum physics and optics. These particles represent the smallest units of electromagnetic radiation, such as light, and they travel at the speed of light in a vacuum. In this market, photons are constantly interacting with matter, absorbing and emitting energy in discrete packets, known as quanta. These interactions occur across various scales, from the interaction of light with atoms and molecules to the collective behavior of light in optical fibers or solar cells. The marketplace is dynamic, with photons flowing into and out of materials, influencing phenomena like refraction, reflection, and absorption, and playing a crucial role in everything from photosynthesis to digital communication technologies.
