Quantization of Energy Part 2: Photons, Electrons, and Wave-Particle Duality

The video explores the concept of quantization, starting with Planck's work and moving to Einstein's seminal papers on Brownian motion, special relativity, and the photoelectric effect. It discusses the photoelectric effect's role in establishing quantization and introduces wave-particle duality, highlighting light's dual nature. The Bohr model is explained, showing energy quantization in hydrogen atoms. The video concludes with de Broglie's matter wave duality, leading to the development of quantum mechanics.
