Quark (2/13)



  1. The Copenhagen Interpretation is one the main important postulate of quantum mechanics, and i would not ignore it.. And to my question that if an electron behave like a particle or wavelength(at a specific period of time), can't be answered, because we don't know what is happening physically inside a particle, unlike classical physics. But yes, we can always draw possibilities about it, that is what quantum physics is about..
  2. This reply was certainly not required.. Are you reffering to Juan?

  4. Studiot, You speak french?? Tres bon!
  5. Then how would you describe a "Particle" in quantum terms and not classical physics??
  6. Yeah, pretty much. Thanks for the knowledge. Even X-Rays were discovered by an accident, but let's not get off topic.
  7. Thanks Juangra. But is electron present as a standing wave or as a particle in the atom?? I have read in some book, that it is still a mystery and we can't figure out what goes inside the atom..
  8. I have heard about the double split experiments, but performed with waves.. Why can't the question related to electrons be answered? Taking electrons on orbits might be wrong, because they are present in quantum number or energy states..
  9. Can you please tell me a bit more in detail??
  10. LIGHT We do know that photons behave like a wave and a particle both, that's what particle wave duality tells us.. 1)So which source of light behave likes a particle and which one like a wave, How do we know that?? 2)If a particle has larger wavelength it behaves like a wave and the one which has smaller wavelength behaves like a photon? 3)Photons have momentum, p=hv/c, do wave have some momentum? Electrons Electrons are present around the nucleus of an atom(we all know that) 4) Are they present there as particles, standing frequency, clouds or on orbits(which is the least i would prefer) ??
  11. Yes, it will accelerate. Photons have do have momentum and they also do have energy, but very little. E=PC P=e/c Substituting E=hv P=hv/c But the amount of momentum will be less and thus it will take a large amount of time to reach to your destination..
  12. An atom is not like a "mini solar system" that you have described above. If electrons followed a specific path and revolved around the nucleus, they ought to radiate energy, which would cause them to collapse (possitive and negative forces attract each other). You are combining "classical" physics with quantum physics...
  13. That is incorrect, considering the fact that photons don't have mass, and they don't occupy space (BOSONS), yet some people consider it at as a "matter" I recommend you do not use this definition of matter..
  14. Yes, it helps a lot.. Thanks for providing the link..

    For example, consider a simple hydrogen atom, basically composed of a single proton. It has a tiny mass indeed. But in everyday quantities of matter there are a lot of atoms! For instance, in one kilogram of pure water, the mass of hydrogen atoms amounts to just slightly more than 111 grams, or 0.111 kg. Hence E=(MC2)2 + p2c2 Simplified E = MC2 = 0.111 x 300,000,000 x 300,000,000 = 10,000,000,000,000,000 Joules Why is the momentum always "0"?
