👉 Light particles, often referred to as photons, are fundamental components of light and electromagnetic radiation. These particles are incredibly small, far smaller than atoms or molecules, and they exhibit both wave-like and particle-like properties, a concept known as wave-particle duality. Photons are massless and travel at the speed of light in a vacuum, making up approximately 99% of the energy carried by electromagnetic waves like sunlight, radio waves, and X-rays. They are crucial in various phenomena, from the way we see the world through vision to the operation of technologies like lasers and fiber optics. Understanding light particles is essential in fields such as physics, astronomy, and materials science, where they help explain everything from the behavior of atoms to the structure of the universe.
