👉 Light particles, often referred to as photons, are fundamental entities that make up light and other forms of electromagnetic radiation. These particles are incredibly small, with wavelengths ranging from about 400 nanometers (violet light) to 700 nanometers (red light), making them invisible to the human eye. Despite their minuscule size, photons possess significant energy and carry momentum, which can be transferred during interactions with matter. They travel at the speed of light in a vacuum, approximately 299,792 kilometers per second, and exhibit both wave-like and particle-like properties, a concept central to quantum mechanics. Photons are crucial in various phenomena, from the photoelectric effect, where they eject electrons from materials, to the functioning of solar cells and fiber optics, enabling communication over long distances. Understanding light particles is essential in fields like physics, chemistry, and engineering, providing insights into the behavior of matter and energy at microscopic scales.
