@ chi volesse rispondere.
Perché Rossi si incarica di rispondere ad una domanda di tal “Curious” (che posterò sotto) fornendo due versioni: filosofica e fisica? La mia è semplicemente una curiosità … oppure sono alla frutta? … ove la seconda fosse più probabile … temo che debba andare dal medico. Anzi, oggi vado dal medico, ma intanto voi:

to who may it concern! As I know, but i could be wrong, it does not exist a complete description of a photon. Even for lower frequencies we can speak about single photon, but I’ve never seen an oscilloscope trace of it. Is it a single wave? or a group a waves increasing and after decreasing following a normal curve or what? And when does it finish and overall start (3-4-5 s or what?) and overall when does it begin? Can you give me some address where to find answer, possibly for ignorant and without too much mathematics
Sorry if this is a stupid question, but I would understand.
Thanks

Curious:
Physics:
A photon is an elementary quantum of light. It cannot be decomposed ( unless it interacts with another elementary particle and becomes another thing) and is stable, therefore is a real particle. It does not respect the Pauli principle and therefore is a Boson. It is characterized with extreme precision by its wavelength and his frequency. Its energy is given by the equation
E = h x f
wherein f is the frequency and h is the Plank constant.
From this equation you can understand that a photon is a precise and indivisible quantum of energy, along the quantistic mechanic. In the everyday life you can distinguish several photons, whose wavelength is within the visible specter: the colors we can see, like red, green, yellow etc are the consequences for our eyes of the different wavelengths of different photons. They travel in the space at the speed of the light, because they are massless. Photons are the bearers of the electromagnetic interactions. The limits or a single photon are defined by the extremes of its wavelength and the corresponding electric and magnetic fields.
Phylosophy:
This description is that of the Standard Model, therefore, sooner or later, is destined to be considered wrong; paradoxically, the fact that in some different condition the Standard Model is falsifiable, make it true and valid ( Popper, Fermat).
