👉 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 and massless, existing as quanta of energy rather than being composed of matter. Each photon carries a specific amount of energy, which is inversely proportional to its wavelength—shorter wavelengths correspond to higher energy photons, such as those in the ultraviolet or gamma-ray spectrum. In practical terms, light particles are the basis for how we perceive light and interact with the world around us, from the colors we see to the energy they carry that can be harnessed for various applications like solar power. Despite their elusive nature, scientists estimate that light particles travel at an incredibly fast speed, approximately 299,792 kilometers per second in a vacuum, making them key players in both everyday phenomena and advanced technologies.
