Sommerfeld refined bohrs theory by incorporating special relativity and the possibility of elliptical orbits. Aug 31, 2016 the waveparticle duality seems to used all the time to explain quantum mechanics to the public, but it is one of my pet peeves. When i conceived the first basic ideas of wave mechanics in 19231924, i was guided by the aim to perform a real physical synthesis, valid for all particles, of the coexistence of the wave and of the corpuscular aspects that einstein had introduced for photons in his. Interpretation of quantum mechanics by the double solution. With the addition of two new quantum numbers, the bohrsommerfeld theory accounted for many features of spectra and showed how the periodic table is built up in a systematic way. This shows that an objects wavelength gets smaller.
Our new crystalgraphics chart and diagram slides for powerpoint is a collection of over impressively designed datadriven chart and editable diagram s guaranteed to impress any audience. Today we know that every particle exhibits both matter and wave nature. The transfer of energy from source to receiver is more. Particlewave duality mit opencourseware free online. Quantum physics i, lecture note 4 mit opencourseware free. A causal interpretation, elsevier publishing company, 1960. So recapping, light can have particlelike or wavelike properties, depending on the experiment, and so. Quantum physics i, lecture note 4 mit opencourseware. Matter waves are a central part of the theory of quantum mechanics, being an example of. Publication date 19300000 topics natural sciences, physics publisher.
Dec 02, 2017 neet physics notes optics matter waves debroglie waves debroglie waves the concept of debroglie waves reflects the waveparticle duality of matter. Chart and diagram slides for powerpoint beautifully designed chart and diagram s for powerpoint with visually stunning graphics and animation effects. Broglies theory, for a particle at rest v0, the phase wave aspect. After albert einsteins photon theory became accepted, the question became whether this was true only for light or whether material objects also exhibited wavelike behavior. Neet physics notes optics matter waves debroglie waves debroglie waves the concept of debroglie waves reflects the waveparticle duality of matter. However, i dont know if there is any theory that supplies the correct technical details. The relationship is now known to hold for all types of matter. Matter waves istituto nazionale di fisica nucleare. Neet physics notes optics matter waves debroglie waves. The debroglie relations shows that the wavelength is inversely proportional to the momentum of a particle and is also called debroglie. The debroglie relations shows that the wavelength is inversely proportional to the momentum of a particle and is also called debroglie wavelength. Hence, the trajectory of a particle is a welldefined concept. After albert einsteins photon theory became accepted, the question became whether this was true only for light or whether material objects also.
Postulation and understanding of waveparticle duality was a controversial topic from the very beginning and is closely enmeshed with the origin and development of the photoelectric effect and quantum theory. Electron microscope is a common instrument illustrating this fact. In addition to a wavefunction on the space of all possible configurations, it also postulates an actual configuration that exists even when unobserved. He sensed deeply the symmetry in nature and argued that if light sometimes behaves like a wave and sometimes like a particle, then perhaps those things i. It was einstein who proposed that waves light could behave like particles photons. We begin with a brief historical summary of this idea and its development. Section 4 is devoted to bohms secondorder formulation of the theory in terms of the socalled quantum potential. Since the electron model is based directly on the special theory of relativity, it may also be used as an illustration of that theory. One then may expect that the closely related notion of inertial trajectory is also unproblematically defined. But then, the wave nature of electromagnetic radiation is called into question when it is involved in blackbody radiation, photoelectric e ect and such.
It features a 1hour lecture video, and also presents the prerequisites, learning objectives, reading assignment, lecture slides, homework with solutions, and resources for further study. So recapping, light can have particlelike or wavelike properties, depending on the experiment, and so can electrons. Obviously in this case, the physical wave cannot be a constant multiple of the statistical wave, since the statistical wave is in configuration space. Uniting the wave and the particle in quantum mechanics springerlink. Interferentieproeven met licht leken dit experimenteel te bevestigen. But then, the wave nature of electromagnetic radiation is called into question when it is involved in blackbody radiation, photoelectric e. This page contains materials for the session on particlewave duality.
This means that everything in the universe can act like a wave. Pilot wave theory and quantum fields philsciarchive. The waves associated with moving matter particles are called matter waves or debroglie waves. Thus, every object in motion has a wavelike character. The problem was that no one had ever seen a particle diffract or interfere with another particle.
