ENGB52H3 Lecture Notes - Lecture 11: Photon, Double-Slit Experiment, Werner Heisenberg
Document Summary
Werner heisenberg: nobel prize in 1932 for quantum mechanics, most famous for the uncertainty principle, german nationalist. Neils bohr: nobel prize in 1922 for quantum theory, the bohr model of the atom and complementarity, danish, half jewish. Describes the behavior of matter and energy at the nanoscopic level. Suggests that the behavior of subatomic particles is random and unpredictable. 2 concepts: complementarity, the uncertainty principle. Complementarity: objects have complementary properties that cannot be known simultaneously such as, bohr. Thomas young"s double slit experiment seems to confirm the wave nature of light. Michelson-morley experiment (1887: a failed attempt to detect the aether wind, without the aether, how could light propagate as a wave, laid the groundwork for special relativity and quantum mechanics. In 1905, einstein publishes his photon theory of light: which proposed that light traveled as discrete bundles of energy or quanta.
