A Brief Analysis of the Wave-Particle Duality of Light

Abstract

This article aims to delve deeply into the important concept of wave-particle duality of light in quantum mechanics. First, the historical development process of the wave-particle duality of light was reviewed, from the early debate between the particle theory and the wave theory, to the predicament of classical physics, and then to the birth and development of quantum theory. Then, the specific manifestations of the wave nature and particle nature of light were elaborated in detail, including wave phenomena such as interference and diffraction, as well as particle nature phenomena such as the photoelectric effect and the Compton effect. Then, a philosophical reflection was conducted on the essence of wave- particle duality, and the relationships between matter and motion, as well as between the microscopic and the macroscopic were explored. Finally, the application of the wave-particle duality of light in modern scientific and technological fields, such as laser technology and quantum communication, was analyzed, emphasizing the profound influence of this theory on the development of science and technology.
