Re: What is the frequency and how is it determined of virtual particles ?

Hello S. Yuri (please forgive the lateness of my reply)!
I am not sure how to answer this. I am (probably) younger than you 
and am not doing a degree, yet, so I could be completely wrong, but 
aren't you mixing up Newtonian mechanics with Quantum 
mechanics. Nonetheless it is nice to see questions like this in 
MadSci net.
Anyway, here's my poor excuse of an answer. If both particles are still 
(constant force on both) they would be exchanging photons (or 
possibly W or Z bosons when at high energies). For example 
(Newtonian terms): if two electrons are a distance, r, from each other, 
they repel. The force of this is calculated by   F = Q1Q2 / 4(pi)(epsilon 
zero)(rr) (Coulomb’s law). If one is still, it must have a force acting on 
it equal and opposite to F (Call this force S - no reason for the letter 
used!). The ‘free’ electron will then move away from the still one. As 
the other electron moves away, r increases, therefore F decreases. 
As S is constant, the previously still electron will move in the same 
direction to the ‘free’ one. If they were an electron and a positron, the 
opposite would happen. I am not sure why the still particle will 
oscillate.
If you were asking why the virtual particle (photon) would oscillated, it 
wouldn’t. As photons can travel at any speed they wish, as they have 
no rest mass, the interaction is instant. See a Feynman diagram and 
I’m sure you’ll agree.
If you were asking how to calculate the frequency (or wavelength) of a 
photon, as a wave(icle), the formula I have been told is E = hf  (where 
E = the energy of the photon, h = Plank’s constant and f = frequency). 
Erm, that is all I think I can tell you, if anything. I don’t feel that I have 
been much help as you are probably dealing with things I have not 
come across yet. If you want to discuss the question further try 
emailing me at paul@jdh.dircon.co.uk as I am interested. If you want 
more expert advice try the MadSci net again and hopefully you’ll get 
an answer from someone who knows a bit more than me! Oh and if I 
am completely wrong, please tell me why.


by the way, I energy is not conserved! As particles can be created in a 
vacuum this is not true. Althogh in most cases it is applicable. 
Apparently, neither pairity nor symmetry are conserved in some weak 
interactions. Just thought you might like to know.
The search for the Higgs boson continues...
