Wave and Particle Properties of Lihgt
Abstract
Some physical effects indicate that light is a motion wave. For example, interference and diffraction. But others, especially in microscopic world, suggest that light has particle-like properties. Since the 17th century, the dispute over the question of the nature of light began. Finally, with 300 years' difficult process, the theory of “wave-particle duality” has won this dispute. What’s the meaning of wave-particle duality? What is the relationship between these natures of light? In this paper, from the knowledge of light’s quality and philosophical methodology, by analyzing the history of wave-particle duality, we explore these two issues. Then, we can understand deeply the development of optics and the thinking of physicists.
