👉 Light particles, also known as photons, are fundamental components of light and other forms of electromagnetic radiation. These particles are incredibly small, much smaller than atoms or molecules, and they carry energy and momentum. Unlike matter particles like electrons, which have mass, light particles have no rest mass. Photons are the quanta of the electromagnetic field, meaning they are discrete packets of energy. They travel at the speed of light in a vacuum, approximately 299,792 kilometers per second, and their behavior is described by quantum mechanics. Light particles can exhibit both wave-like and particle-like properties, a concept known as wave-particle duality. This dual nature is a cornerstone of modern physics, explaining phenomena such as interference and diffraction in the context of light.
