The discussion clarifies that photons are not contained within electrons but are generated through interactions with the electromagnetic field. When charged particles, such as electrons and protons, accelerate or change states, they create photons as a result of energy and momentum exchange. The concept of photons being "created" or "destroyed" is misleading, as it is more accurate to describe them as energy exchanges occurring at specific times and locations during interactions with matter.
PREREQUISITESPhysicists, students of quantum mechanics, and anyone interested in the fundamental interactions between light and matter will benefit from this discussion.
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.
