👉 Light particles, or photons, are fundamental components of electromagnetic radiation and are often described as massless, point-like entities that carry energy and momentum. These particles are the quanta of light, meaning they exist in discrete packets rather than as continuous waves. Photons are emitted when atoms or other charged particles transition between energy levels, such as when an electron jumps from a higher energy state to a lower one. They travel at the speed of light in a vacuum, approximately 299,792 kilometers per second, and their behavior is governed by quantum mechanics. Photons interact with matter through processes like absorption, emission, reflection, and refraction, playing crucial roles in phenomena ranging from photosynthesis to the functioning of optical devices and the transmission of information via fiber optics. Despite their lack of mass, photons exhibit properties of both particles and waves, making them central to our understanding of light and its interactions with the physical world.
