Scattering, as the name implies, has to do with the deflection of
radiation, not with its emission or absorption.
Radiation is deflected because photons are absorbed and emitted.
That is not what wiki says.
There
is even a nice picture of a Feynman diagram, in the article you cited,
So what? It is a Feynmann diagram of an electron-electron interaction
via the theoretical construct of a virtual photon exchange. I fail to
see what that has to do with the scattering, or emission, or
absorption, of real photons.
Plus the answer to your
question in the other post.
I am not psychic. Which question, and which post?
Why don't you read it?
If you mean the wiki article, I have now read it a second time. I
suggest you now read it and point out where it says what you think it
says.
Re: |GG| Re: The Joy of Pixel Density ... There is not much variation in the total number of photons capturable per unit of area; most of the variation is in the rate they are caught. ... These include the absorption length in silicon, ... limiting the maximum number electrons captured in a semiconductor ... So an I understand from that, small pixels get muddled data from deeper penetrating photons as they cross under to adjacent pixels. ... (rec.photo.digital)
Re: Wave as wave, particle as particle ... When photon numbers are counted each emission or transition event is merely *assumed* to be caused by one photon, the number of events then counted and assumed to equal the number of photons.... In experiments that intend to measure interference effects, such as in the double slit experiment, you are measuring interference of light and thus the properties of light called phase and/or polarity, I see no integer numbers associated with those qualities, only angles. ... Though QM provides a counterpart to classical wave addition, it provides no mechanism, it is thus nothing more than a renaming the classical parameters along with the claim that they are nonclassical. ...
