matter waves

matter waves : In quantum mechanics, a matter wave or de Broglie wave (pronounced /dəˈbrɔɪ/) is the wave ( wave-particle duality) of matter. The de Broglie relations show that the wavelength is inversely proportional to the momentum of a particle and that the frequency is directly proportional to the particle's kinetic energy. The wavelength of matter is also called de Broglie wavelength. The theory was advanced by Louis de Broglie in 1924 in his PhD thesis; he was awarded the Nobel Prize for Physics in 1929 for this work, which made him the first person to receive a Nobel Prize on a PhD thesis. After strides made by Max Planck (1858-1947) and Albert Einstein (1879-1955) in understanding the behavior of electrons and what would be known as quantum physics, Niels Bohr (1885-1962) began (among other things) trying to explain how electrons behave. He came up with new fundamental ideas about electrons and mathematically derived the Rydberg equation, an equation that was....   More from Wikipedia

matter waves : The term matter traditionally refers to the substance that objects are made of. One common way to identify this "substance" is through its properties: for example, matter is anything that has both mass and volume. A more general view is that bodies are made of several substances, and the properties..   More from Wikipedia

matter waves : In physics and chemistry, wave-particle duality holds that light and matter exhibit properties of both waves and of particles. See also: Matter & Energy Quantum Physics Physics Optics Inorganic Chemistry Albert Einstein Quantum Computing A central concept of quantum mechanics, duality addresses the inadequacy of conventional concepts like "particle" and "wave" to meaningfully describe the behaviour of quantum objects. The idea of duality is rooted in a debate over the nature of light and matter dating back to the 1600s, when competing theories of light were proposed by Christiaan Huygens and Isaac Newton. Through the work of Albert Einstein, Louis de Broglie and many others, it is now established that all objects have both wave and particle nature (though this phenomenon is only detectable on small scales, such as with atoms), and that a suitable interpretation of quantum mechanics provides the over-arching theory resolving this ostensible paradox..

  Matter is made of spherical standing waves. A standing wave is a wave that may be thought of as two waves traveling in opposite directions. For a particle, this means an incoming wave converging o the centre and an outgoing wave coming out of the centre, which is just the incoming wave after it travels through the centre. Seeing matter as real waves rather than just probabilities is consistent with the thinking of Schroedinger and de Broglie who established the important formula for the ...

  electron decided to act differently. As if it was aware it was being watched! And it was here that physicists stepped forever into strange, never world of quantum events. What is matter? Marbles or waves? And waves of what? And what does an observer does have to do with any of this? The observer collapsed the wave function by simply observing! --- It's Never too Late to Study: www.FreeScienceLectures.com --- Notice This video is copyright by its respectful owners.

Question : Teacher said electrons are waves (DeBrolie)and we computed wavelength of an electron moving fast. He said electron microscope use electron waves to see tiny things. I asked if the matter waves were electromagnetic. He said no they are matter waves. I asked if they are not electromagnetic how can we observe them in a microscope. He said ... he did not know. Could you please help me?

Answer : An electron microscope bounces electrons off of things, captures them as they bounce off and then resolves a picture from the distribution of electrons that have returned. This is the same way a light bounces off stuff and we capture the reflected photons to make a picture with our eye. We cant see electrons with our eyes, though, so we need a machine to collect the scattered electrons and a computer to put an image together based on how the electrons scattered. The reason electrons can be used to see smaller things is that they have a "shorter wavelength" than visible light. The debroglie wavelength isn't a complete description of the wave properties of an electron or pohoton, but it is a good way to approximate many things. The wave function that describes an electron or a photon, or anything else is NOT a "matter" wave. That is a poor description. The wave itself is related to the probability that you will find the electron at a certain point in space, or with a certain....   More from Yahoo Answers

Question : Start from as simple as you can .

Answer : The problem when you ask for an actual picture is that you are asking for an intuitive, easy-to-visualize representation of something that isn't intuitive of easy to visualize. Anyone that can draw you a picture or give you a quick answer or analogy has to be leaving out a lot. Here's the deal. In classical mechanics, particles behave a certain way--they have definite positions and momenta and propagate in predictable ways. But classical mechanics fail at the microscopic level. In fact, particles like electrons obey quantum mechanics. They are described by a complex function which dictates probability distributions for their positions and momenta, which are no longer exactly knowable. In non-relativistic situations, that function obeys a differential equation called the schrodinger equation. This equation is similar in some ways to a classical wave equation. Consequently, the solutions are wave-like in many respects--so we call them wave functions. Particles such as electro....   More from Yahoo Answers
