The Nature of Light: From Newton’s Corpuscular Theory to de Broglie’s Dual Nature
What is light — a particle or a wave? This comprehensive guide traces the fascinating evolution of the nature of light, starting from Newton’s corpuscular theory in 1672 through Huygens’ wave theory, Maxwell’s electromagnetic theory, Einstein’s photon concept, and finally de Broglie’s revolutionary dual nature of matter and radiation. Includes a detailed comparison table of…
