Another obvious clue being that the electron itself has a 'Compton' wavelength (named after American experimental physicist Holly Compton who discovered this from experiments with electron beams). But unfortunately they had come to accept the particle wave duality of matter and simply continued to assume that somehow this...http://physics-physicsdiscussion.blogspot.com/2007/11/13-quantum-theory-compton-wavelength... 1.2 Quantum Theory Mechanics: de Broglie's Discovery of the Wave Properties of Electrons (1927)- November 26, 2007 1.2 Quantum Theory Mechanics: de Broglie's Discovery of the Wave Properties of Electrons (1927)The next step was taken by de Broglie. He asked himself how the discrete states could be understood by the aid of current concepts, and hit on a parallel with stationary (standing) waves, as for instance in the case of proper frequencies of organ pipes and strings in acoustics. (Albert Einstein, 1954)It is with some frustration that I now read these quotes, as it is obvious in hindsight as to their...http://physics-physicsdiscussion.blogspot.com/2007/11/12-quantum-theory-mechanics-de-brogl... 1.1 Quantum Physics Foundations: Max Planck's Discovery of Particle Quantum Properties of Light (1900)- November 23, 2007 1.1 Quantum Physics Foundations: Max Planck's Discovery of Particle Quantum Properties of Light (1900)In 1900 Max Planck made a profound discovery. He showed (from purely formal mathematical foundations) that light must be emitted and absorbed in discrete amounts if it was to correctly describe observed phenomena (i.e. Blackbody radiation). Prior to then light had been considered as a continuous electromagnetic wave, thus the discrete nature of light was completely unexpected, as Albert...http://physics-physicsdiscussion.blogspot.com/2007/11/11-quantum-physics-foundations-max_2... Introduction to Quantum PhysicsQuantum Theory Wave Mechanics- November 20, 2007 Introduction to Quantum PhysicsQuantum Theory Wave MechanicsFrom 1900 to 1930 there was a revolution in the foundations of our understanding of light and matter interactions. In 1900 Planck showed that light energy must be emitted and absorbed in discrete 'quanta' to explain blackbody radiation. Then in 1905 Einstein showed that the energy of light is determined by its frequency, where E=hf. Finally, in the late 1920s, de Broglie and Schrodinger introduced the concept of Standing Waves to...http://physics-physicsdiscussion.blogspot.com/2007/11/introduction-to-quantum-physicsquant... Quantum Physics- November 17, 2007 On the one hand the quantum theory of light cannot be considered satisfactory since it defines the energy of a light particle (photon) by the equation E=hf containing the frequency f. Now a purely particle theory contains nothing that enables us to define a frequency; for this reason alone, therefore, we are compelled, in the case of light, to introduce the idea of a particle and that of frequency simultaneously. On the other hand, determination of the stable motion of electrons in the atom...http://physics-physicsdiscussion.blogspot.com/2007/11/quantum-physics.html |
