👉 Light particles, often referred to as photons, are fundamental units of electromagnetic radiation that exhibit both wave-like and particle-like properties. These particles are massless and travel at the speed of light in a vacuum, approximately 299,792 kilometers per second. Despite their lack of mass, photons carry energy and momentum, which can be transferred to matter through interactions such as absorption or emission. This dual nature is encapsulated in quantum mechanics, where light is described as both a wave and a stream of discrete energy packets. 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, highlighting their essential role in both natural processes and technological applications.
