The study of visible light—a narrow band of electromagnetic radiation perceptible to the human eye—has evolved dramatically since its early philosophical roots. From Isaac Newton’s pioneering prism experiments to today’s quantum mechanical models, our understanding of light’s spectral properties has revolutionized fields as diverse as optics, astronomy, and lighting design. This article...

To comprehend light’s role in both natural phenomena and human applications, it is essential to explore the visible spectrum—the narrow band of electromagnetic radiation detectable by the human eye. While scientific interpretations of light’s interaction with human perception continue to evolve, established principles and properties provide a robust framework for understanding its nature....
