The Nature of Light: Particles and Waves

This chapter explores the historical debate surrounding the nature of light, tracing its conceptual evolution from ancient particle theories to wave interpretations. It highlights key figures like Descartes and Newton, the implications of significant experiments such as the double slit experiment, and the emergence of quantum mechanics to explain light's dual behavior. The discussion emphasizes the importance of experimental verification in shaping scientific understanding and how early limitations in methodology influenced theories about light.
