👉 Light particles, often referred to as photons, are fundamental components of electromagnetic radiation, including visible light. 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, they carry energy and momentum, which can be transferred to matter through interactions such as absorption or reflection. Photons are the quanta of light, meaning they exist in discrete packets rather than as continuous waves. This particle nature of light is crucial in explaining phenomena like the photoelectric effect, where light can eject electrons from a material, and in understanding how light interacts with atoms and molecules, influencing processes such as photosynthesis and the operation of optical devices.
