👉 Light particles, often referred to as photons, are fundamental entities that exhibit both wave-like and particle-like properties. These particles are the smallest units of light and electromagnetic radiation, traveling through space at an incredibly high speed—approximately 299,792 kilometers per second in a vacuum. Unlike matter particles, which have mass and can be affected by forces like gravity and friction, light particles are massless and interact primarily through electromagnetic forces. This unique characteristic makes them invisible to the naked eye but detectable through their effects on matter and other electromagnetic waves. Photons are crucial in various phenomena, from the photoelectric effect, which underpins solar panels, to the behavior of stars and galaxies, where they carry energy and information across vast cosmic distances. Their study is fundamental to understanding quantum mechanics and the nature of light itself.
