👉 Light particles, also known as photons, are fundamental units of light that exhibit both wave-like and particle-like properties. These tiny packets of energy travel through space at an incredibly fast speed, approximately 299,792 kilometers per second in a vacuum. Each photon carries a specific amount of energy, which is directly proportional to the frequency of the light it represents—higher frequency means more energy. Unlike matter particles like electrons, photons do not have mass and move in straight lines unless acted upon by an external force, such as gravity or another photon. This unique nature makes them crucial in various phenomena, from the photoelectric effect, where light can eject electrons from a metal surface, to the functioning of lasers and fiber optics, where they transmit information over long distances with minimal loss.
