PHYS 201 - Fundamentals of Physics II
Lecture 19 - Quantum Mechanics I: Key experiments and wave-particle duality. The double slit experiment, which implies the end of Newtonian Mechanics, is described. The de Broglie relation between wavelength and momentum is deduced from experiment for photons and electrons. The photoelectric effect and Compton scattering, which provided experimental support for Einstein's photon theory of light, are reviewed. The wave function is introduced along with the probability interpretation. The uncertainty principle is shown to arise from the fact that the particle's location is determined by a wave and that waves diffract when passing a narrow opening. (from oyc.yale.edu)
