Magical Realist, Nov 5, 1:24 PM What electromagnetic force do photons carry? If a photon flies past an electron, is it attracted to that electron by a force? Does a photon carry a force that is imparted to the electron? How does this "force" exist in a massless particle? Isn't ALL energy equivalent to mass?
Russ_Watters, Nov 6, 4:58PM Magical Realist said: ↑ Objects don't "carry force". Force is an interaction between objects. But no, photons do not interact with electrons in this way: they have to hit the electron. "Equivalent" and "is" are two completely different things. Yes, mass and energy are equivalent. But energy is not mass and vice versa.
Q-reeus, Nov 6, 5:34PM It's not correct that identical frequency/wavelength means indistinguishability. Numerous times this forum, one member has brought up that coherence length of photons with the same E = hf can vary enormously, depending on source. Also, photons can exist in different modes.
Q-reeus, Nov 6, 5:40PM Massless photons carry momentum |p| = E/c = hf/c : http://hyperphysics.phy-astr.gsu.edu/hbase/relativ/relmom.html
I posted this. Why is it coming up as Q-reeus having posted it?! Does it appear this way for everyone else?! Weird....
Well, no...photons do not have charge so they will not be attracted to the electron that way. It carries energy which has the ability to produce force Photons do not have any mass, only energy.
Aha, I see. I guess I don't even know who I'm replying to anymore (until they sort it out) Please Register or Log in to view the hidden image!
