Quantum Mechanics and Light Phenomena

The video explores the dual nature of light, acting as both particles and waves, which is central to quantum theory. It traces the historical development of light theories, from Newton's corpuscular theory to Maxwell's electromagnetism, leading to the quantum revolution. Key contributions by Max Plank and Albert Einstein are highlighted, including energy quantization and the photoelectric effect. The wave-particle duality is demonstrated through the double slit experiment. The video concludes with the technological advancements enabled by quantum theory, such as lasers, LEDs, and quantum computing.
