Description

This lecture covers the failure of classical theory in describing thermal radiation, the UV catastrophe, derivation of Planck's radiation law, and Einstein's quantum model with A & B coefficients. It also discusses transition rates, absorption, stimulated and spontaneous emission, and the relation between Einstein and Planck. The lecture delves into rate equations, absorption and emission spectra, lifetimes, and the saturation of population.
