👉 The free-light particles, often referred to as photons, are fundamental quanta of electromagnetic radiation. They represent the smallest units of light and other forms of electromagnetic waves, such as radio waves and X-rays. Photons are massless, traveling at the speed of light in a vacuum, and they carry energy and momentum proportional to their frequency. In essence, free-light particles are the particles that mediate the electromagnetic force, allowing charged particles to interact with each other through the exchange of these energy packets. This concept is central to quantum mechanics and plays a crucial role in phenomena ranging from the behavior of atoms to the functioning of solar cells and lasers.
