Quantum physics i, lecture note 4 mit opencourseware. Select multiple pdf files and merge them in seconds. The equation further explains that a beam of electrons can also be diffracted just like a beam of light. Next, eliminate e by introducing kinetic energy, then use the fact that kev. It seemed reasonable to wonder if electrons could also have a dual waveparticle nature. In fact radiation shows dual nature sometimes as wave and sometimes as particle. Interpretation of quantum mechanics by the double solution. It means when the matter is moving it shows the wave properties like interference, diffraction etc. Matter wave simple english wikipedia, the free encyclopedia. But in the end one cannot derive this relationship. Chapter 41 wave mechanics national tsing hua university. Plancks investigation of the emission spectra of hot objects and the subsequent studies into the photoelectric effect had proven that light was capable of behaving both as a wave and as a particle.
So, matter should have wave which can be expressed as. He published his work in 1925 in a breakthrough paper. The tentative, even if interesting, ideas of mie are thusly doomed. Matter waves are hard to visualize, because we are used to thinking of matter as a physical object. There is no chance of observing wave phenomena, such as diffraction, with macroscopic objects. Thus, every object in motion has a wavelike character. In the subsequent series of papers with max born and pascual jordan, during the same year, this matrix formulation of.
Relation between electric potential and wavelength of an. We went to speak to tony short and nazim bouatta, both theoretical physicists at the university of cambridge, to find out. According to debroglie hypothesis, the energy of the universe is in the form of matter and radiation. Closely following the electromagnetic prototype of a wave equation, and attempting to describe the electron relativistically, he. Merge pdf files combine pdfs in the order you want with the easiest pdf merger available. In his 1924 phd thesis, he postulated the wave nature of electrons and suggested that all matter has wave properties. So, both matter and radiation should have the similar properties. The trouble is that the velocity youre calculating using the kinetic energy is the group velocity not the phase velocity, so your equation cant be applied to the electron. Moreover, they do not explain why electricity has an atomised structure. But how should we interpret its solution, the wave function. Electron microscope is a common instrument illustrating this fact.
