👉 Light particles, often referred to as photons or massless particles of electromagnetic radiation, are fundamental entities that carry energy and momentum through space. These particles are the quanta of the electromagnetic field and can exist independently, though they are most commonly associated with light, such as sunlight or artificial sources like LEDs and lasers. Photons are characterized by their massless nature, which allows them to travel at the speed of light in a vacuum, approximately 299,792 kilometers per second. They interact with matter primarily through electromagnetic forces, enabling phenomena like reflection, refraction, and absorption. In quantum mechanics, photons are described as having both particle-like and wave-like properties, making them central to understanding light's behavior in various contexts, from classical optics to quantum electrodynamics.
