👉 Light particles, also known as photons, are fundamental entities that exhibit both wave-like and particle-like properties, a concept central to quantum mechanics. These tiny packets of energy travel through space at an incredibly fast pace, typically at the speed of light, approximately 299,792 kilometers per second in a vacuum. Each photon carries a specific amount of energy, which is inversely proportional to its wavelength—shorter wavelengths mean higher energy. Despite their minuscule size, photons can interact with matter, causing phenomena such as reflection, refraction, and absorption, while also being emitted by excited atoms or molecules. This dual nature of light particles—both as waves and as discrete packets of energy—explains many of the unique behaviors observed in optics and quantum physics.
