👉 Modern light particles, often referred to as photons, are fundamental quanta of electromagnetic radiation. Unlike classical particles, photons exhibit both wave-like and particle-like properties, a concept encapsulated by wave-particle duality. They are massless, traveling at the speed of light in a vacuum, and carry energy proportional to their frequency, as described by Planck's equation. Photons are essential in various phenomena, from the emission and absorption of light in atoms to the operation of lasers and solar cells. In quantum mechanics, photons play a crucial role in interactions between matter and electromagnetic fields, underpinning technologies like fiber optics, quantum computing, and advanced imaging techniques. Their behavior is governed by quantum field theory, which describes how these particles interact with each other and with matter at the most fundamental levels.
