👉 Light particles, or photons, are fundamental components of light and other forms of electromagnetic radiation. They are massless, traveling at the speed of light in a vacuum, and carry energy and momentum. Photons are created and emitted by various sources, such as stars, lasers, and even atoms when they transition between energy levels. Despite their lack of mass, photons exhibit both wave-like and particle-like properties, a concept known as wave-particle duality. This duality is central to quantum mechanics, explaining phenomena like the photoelectric effect and interference patterns.
