Quantum Mechanics | The Hydrogen Line Spectrum

The video tutorial explains the hydrogen emission spectrum experiment, where hydrogen gas in a discharge tube is activated by an electric current, causing it to emit light. This light, when passed through a prism, shows discrete spectral lines, indicating quantized energy levels. The experiment is replicated with other elements like sodium and helium, confirming that energy is quantized, not continuous. Historical experiments like the ultraviolet catastrophe and photoelectric effect are linked to the development of quantum mechanics. The video concludes by suggesting further exploration of quantum mechanics postulates.
