Quantum Mechanics: Atomic Spectra

This lecture delves into the principles of quantum mechanics, focusing on the atomic spectra and the failures of classical mechanics to explain them. Starting with the challenges faced by classical mechanics in describing the atom, the instructor covers topics such as the continuous spectrum of light, the discrete spectrum of hydrogen, the Bohr model, and the experiments that led to the development of quantum mechanics. Through discussions on the blackbody radiation model, the photoelectric effect, and the quantization of energy, students gain insights into the corpuscular nature of light and the quantized behavior of energy in atoms.
