O Alta teorie a efectului fotoelectric

calahan:
In fisier se argumenteaza ca facand calculele cu formula data in teoria oficiala, se vede ca nu se respecta conservarea energiei si impulsului simultan, in timpul interactiunii fotonului cu electronul. Si se imagineaza un mecanism care sa asigure conservarea simultana a energiei si impulsului fotonului incident, la interactiunea cu electronul din substanta. Apoi se imagineaza un mecanism de diviziune a fotonilor gama, prin care apare fotonul de frecventa mica, dar si un impuls electric care accelereaza electronul puternic legat in atom, in acord cu teoria lui Compton. Aceste mecanisme sunt imaginate pe baza modelelor, la care a ajuns, asupra structurilor dinamice ale fotonului si electronului.

Ce-i aia energie ? Ce-i ala impuls ? Ce-i ala foton ? Ce-i ala electron ?

Hai sa glumesc: Ce este sau poate e totusi mai bine sa spun Cine este Cosmin Visan? :)

Ma mira tare ca dumneata sa nu ai idee de aceste concepte fundamentale in fizica. Energia este energia cinetica a particulei data de produsul (m*v2)/2, impulsul particulei este dat de relatia  m*v. In aceste relatii v este viteza luminii in vid=c. Fotonul, dupa modelul d-lui inginer ar fi o 
 structura dinamica similara motorolui electric liniar. Iar electronul ar fi o structura dinamica similara motorului electric rotativ bipolar, adica ar fi un rotor cu doi poli care se roteste cu turatia egala cu frecventa fotonului gama de la anihilarea electronului cu pozitronul. Sau ar fi o unda stationara de mare amplitudine, care se propaga (se roteste) pe cercul de raza electronului cu viteza  c/137 (m/s). Legile conservarii impulsului si energiei, spun ca in cursul interactiunii fotonului cu electronul, acei parameri ai fotonului incident se regasesc in parametrii particulelor aparute in urma interactiunii.

1) "In physics, energy is the quantitative property that must be transferred to an object in order to perform work on, or to heat, the object.[note 1] Energy is a conserved quantity; the law of conservation of energy states that energy can be converted in form, but not created or destroyed. The SI unit of energy is the joule, which is the energy transferred to an object by the work of moving it a distance of 1 metre against a force of 1 newton."
2) "In classical mechanics, impulse (symbolized by J or Imp) is the integral of a force, F, over the time interval, t, for which it acts. Since force is a vector quantity, impulse is also a vector quantity. Impulse applied to an object produces an equivalent vector change in its linear momentum, also in the same direction. The SI unit of impulse is the newton second (N⋅s), and the dimensionally equivalent unit of momentum is the kilogram meter per second (kg⋅m/s). The corresponding English engineering units are the pound-second (lbf⋅s) and the slug-foot per second (slug⋅ft/s)."
3) "The photon is a type of elementary particle. It is the quantum of the electromagnetic field including electromagnetic radiation such as light and radio waves, and the force carrier for the electromagnetic force. Photons are massless,[a] and they always move at the speed of light in vacuum, 299792458 m/s."
4) "The electron is a subatomic particle, symbol e− or β−, whose electric charge is negative one elementary charge.[9] Electrons belong to the first generation of the lepton particle family,[10] and are generally thought to be elementary particles because they have no known components or substructure.[1] The electron has a mass that is approximately 1/1836 that of the proton.[11] Quantum mechanical properties of the electron include an intrinsic angular momentum (spin) of a half-integer value, expressed in units of the reduced Planck constant, ħ. Being fermions, no two electrons can occupy the same quantum state, in accordance with the Pauli exclusion principle.[10] Like all elementary particles, electrons exhibit properties of both particles and waves: they can collide with other particles and can be diffracted like light. The wave properties of electrons are easier to observe with experiments than those of other particles like neutrons and protons because electrons have a lower mass and hence a longer de Broglie wavelength for a given energy."
