Einstein's Particle Model in Quantum Light Physics

The theory posits that electromagnetic radiation propagates not only as a continuous wave but also consists of discrete energy packets known as quanta (photons). This principle establishes light emission and absorption as quantized events proportional to frequency, resolving discrepancies between classical thermodynamics regarding blackbody radiation and experimental observations such as the photoelectric effect. The concept defines the domain of quantum optics within physics by unifying particle-like behavior with wave phenomena through energy distribution mechanisms analogous to ideal gases.
