The discussion revolves around the nature of photons in relation to electrons, specifically questioning whether photons exist within electrons or are produced externally. Participants explore the origins of photons, their relationship with electromagnetic fields, and the processes involved in their emission and absorption.
Participants do not reach a consensus on whether photons exist within electrons or are produced externally. Multiple competing views remain regarding the nature and origin of photons, as well as the implications of their interaction with matter.
The discussion includes unresolved questions about the definitions and assumptions surrounding photons and their interactions with electromagnetic fields and matter. There is a lack of clarity on the conditions under which photons are considered to be created or absorbed.
Drakkith said:No, photons are not inside of electrons. They are created by changes in the electromagnetic field, which in turn are generated by the acceleration of charged particles (like electrons and protons) along with changes in their states when bound together (as in atoms and molecules).
Nothing creates them - in fact, for most realistic physical systems there's not even a meaningful notion of how many photons are present, so talking about creating and destroying them makes little sense.rickyyeungyeung said:so which kind of substance produce them?
thanks so much for the reply, so what you mean photonNugatory said:Nothing creates them - in fact, for most realistic physical systems there's not even a meaningful notion of how many photons are present, so talking about creating and destroying them makes little sense.
When an electromagnetic field interacts with matter there's an exchange of energy and momentum between the two; it turns out that this exchange always transfers discrete amounts of energy and momentum at a single time and place. When this happens we say, depending on the direction of transfer, that "a photon was absorbed" or "a photon was emitted" at that time and place.
thx so much for the reply, what u mean photon is just a kind of energy exchanged within atoms and electricmagnetic field, so what i can day photons either located in electricmagnetic field or atoms ,is that correct?Nugatory said:Nothing creates them - in fact, for most realistic physical systems there's not even a meaningful notion of how many photons are present, so talking about creating and destroying them makes little sense.
