Lecture 75 : Experimental Verification of Maxwell's Law

📘 Lecture | Experimental Verification of Maxwell–Boltzmann Law Doppler Broadening | Stern’s Experiment | Zartman & Ko Experiments In this lecture, we study the experimental verification of the Maxwell–Boltzmann velocity distribution law, which confirms the statistical description of molecular speeds in gases. While the distribution is derived theoretically from kinetic theory and classical statistics, its validity has been tested experimentally through both indirect and direct measurements. This lecture discusses the major experimental evidences in a clear and structured manner. Topics covered: • Concept of experimental verification of Maxwell–Boltzmann law • Doppler broadening of spectral lines (indirect evidence) • Thermal motion and frequency shift interpretation • Stern’s molecular beam experiment (1920) – first direct measurement • Measurement of molecular velocity distribution • Zartman and Ko experiments – improved direct verification • Agreement between theory and experiment This lecture bridges theoretical statistical mechanics with real laboratory evidence, making it extremely important for conceptual clarity and competitive exams.
