In that case, we can say that equation 1 and 2 represent the same quantity. This means that photons, electrons possess both momentum as well as wavelength. Deriving time dependent schrodinger equation from wave. Worlds best powerpoint templates crystalgraphics offers more powerpoint templates than anyone else in the world, with over 4 million to choose from. Bardapurkar 32 introduction quantum mechanics is an essential part of undergraduate syllabus in physics as well as in chemistry. A general relation between membrane potential, ion. The equation further explains that a beam of electrons can also be diffracted just like a beam of light. This means that a microscope using electron matter waves instead of photon light waves can see much smaller things. Sommerfeld refined bohrs theory by incorporating special relativity and the possibility of elliptical orbits. Before i derive the equation, it is important to understand the debroglie hypothesis which i am sure. This work is licensed under a creative commons attributionnoncommercialsharealike 4. That means that in order for it to work, your object must have some mass which can be seen in the equation of the wavelength being equal to plancks constant over momentum. We show how special relativity sets tight constraints on the form of possible relations that may exist between the fourmomentum of a particle and the wave fourvector. We know that light can be a wave as well as a particle.
This proved relation is also known as the debroglie equation. There must be a correct way of deriving it for electrons etc. Both light and matter behave like a wave on a large scale and like a particle on a small scale. 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. This equation simply relates the wave character and the particle character of an object. 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. Derivation of the nonlinear schrodinger equation from. Winner of the standing ovation award for best powerpoint templates from presentations magazine. Therefore, chemist, debroglie suggested that if we substitute the velocity of the particles in place of the velocity of the light, then this equation can be valid for the particles too. The debroglie equations can be derived from the einsteins famous equation of energymass equivalence and planks theory of quantum radiation. But in the end one cannot derive this relationship. Bohr model energy levels derivation using physics video. Thanks for contributing an answer to physics stack exchange.
More specifically, we demonstrate that there is just one way, according to special relativity, to relate the finite energy and momentum of a corpuscle with the characteristics of a plane wave, frequency, wave vector. We start with the basic wave equation 1 which is at the base of most of quantum mechanics, including heisenbergs uncertainty principle, schrdingers equation, the relativistic klein gordon equation, etcetera. I understand the concepts but just cant piece them together in this way. The theory of matter waves was used to justify quantization of. For larger objects, the wavelength gets smaller with the increasing size of the object, quickly becoming so small as to become unnoticeable which is why. Electron microscope is a common instrument illustrating this fact. The wavelength of the wave depends on the mass and the velocity of the particle. Thus, every object in motion has a wavelike character. Theyll give your presentations a professional, memorable appearance the kind of sophisticated look that todays audiences expect. A general relation between membrane potential, ion activities, and pump fluxes for. Matter, though it can behave like particles, also behaves like a wave. It is represented by the wavelength of a wave traveling at constant speed is given by.
Chart and diagram slides for powerpoint beautifully designed chart and diagram s for powerpoint with visually stunning graphics and animation effects. And so were gonna be talking about energy in this video, and once again, theres a lot of derivation using physics, so you can jump ahead to the next video to see what we come up with in this video, to see how its applied. And so were gonna be talking about energy in this video, and once again, theres a lot of derivation using physics, so you can jump ahead to the next video to see what. If we continue with our bohr model, the next thing we have to talk about are the different energy levels. The emergence of the evansvigier fieldb 3 of vacuum electromagnetism has been accompanied by a novel charge quantization condition inferred from 03 gauge theory. Deriving time dependent schrodinger equation from wavemechanics, schrodinger time independent nilesh p. Aug 01, 2012 more specifically, we demonstrate that there is just one way, according to special relativity, to relate the finite energy and momentum of a corpuscle with the characteristics of a plane wave, frequency, wave vector and amplitude. This page contains materials for the session on particlewave duality. The hj equation is used with the charge quantization condition to. Next, eliminate e by introducing kinetic energy, then use the fact that kev. By rearranging the momentum equation stated in the above section, we find a relationship between the wavelength. For nonrelativistic quantum physics the basic equation to be solved is the schr odinger equation. For the love of physics walter lewin may 16, 2011 duration. The energy is found to be dependent on the phase change rate in time given by the frequency f.
