👉 Light particles, often referred to as photons, are fundamental entities in physics that describe the quanta of electromagnetic radiation. These particles are characterized by their massless nature and extremely small size, typically on the order of about 4 × 10^-27 meters. Photons are the primary carriers of light and other forms of electromagnetic radiation, such as radio waves and X-rays, traveling through space at the speed of light (approximately 299,792 kilometers per second). They exhibit both wave-like and particle-like properties, a concept central to quantum mechanics. Photons can be emitted or absorbed by atoms and molecules, playing a crucial role in various phenomena, including photosynthesis, the operation of solar cells, and the functioning of optical devices like lasers and photodetectors. In essence, light particles are the building blocks of electromagnetic radiation, facilitating communication, energy transfer, and the interaction of matter with light across the universe.
