I know that a charged particle emits photons which are the "carriers" of the electric and magnetic fields, and that these photons, interacting with another charged particle, cause an attractive force or a repulsive force. I also know that examining the amount of energy in the photons - which are the quantas of light radiation - is basically synonymous with looking at the frequency of the light waves. BUT I also know that the same type of electromagnetic radiation can be emmited as heat radiation such as the lamp in my room. I cannot understand how these concepts work together. I guess my first questions would be: Does the light coming from the lamp in my room carry E and B field force potential? i.e if there was a floating electron right here would it be affected by these photons? If not, then why not? how do you characterize the difference between these heat emitted photons and the "type" of photons that are the carriers of the E and B forces? If yes, then please explain how to reconcile culoumbs law with this. i.e how do you represent a force inversely related to distance squared with photons? And is there a relation between the quanta of energy of the photons ( the frequency) and the strength of the EM field? Assuming that these photons that are emmited from my lamp can not affect a charged particle - then how do you characterize the difference between them and the "type" of photons that are the carriers of the E and B forces? Thanks for any input.
