You seemed to be saying a 500 nm photon is 'to big' to be absorbed by an electron, which is wrong and silly. Perhaps I was mistaken about what you meant. So is there some other reason you said, "How is this possible?"
"Absorbed by an electron" is one root of his many misconceptions.
Yes, 500 nm photon is nowhere near 5.6 billion times bigger, more like 168 million times bigger.
A photon with a wave length of 500 nm is not 500 nm long.
How does it supposed to be interpreted?

A photon with a wave length of 500 nm is not 500 nm long. I'm not sure where you got that idea but you should discard it as soon as possible
That frequency is the rate at which the magnetic and electric field of the photon oscillate from a maximum to a minimum and back to a maximum.
Wavelength does seem to matter in certain situations
FYI, circularly polarized light has a constant amplitude of electric field when propagating as a plane wave. Only the orientation rotates.
This, in spite of many illogicalities and oversights.
Quote from: hamdani yusuf on 20/03/2024 01:57:02How does it supposed to be interpreted?Photons have a frequency. That frequency is the rate at which the magnetic and electric field of the photon oscillate from a maximum to a minimum and back to a maximum. The higher the frequency the higher the energy carried by the photon. A photon with a wave length of 500nm means the photon has a frequency of about 6 x 10^14 cycles per second.Therefore this means when when a photon has traveled the distance of 500nm the magnetic and electric fields will have completed one cycle (such as a maximum to maximum). So the wave length has absolutely nothing to do with the size or length of the photon, it only addresses the rate of the oscillating fields.
Light only travels at c through vacuum. In other media, it travels slower, and the wavelength reduced accordingly, with the same frequency. It does have something to do with length, as the name correctly suggests.

Please supply any reputable source (not a youtube) that says the size of a photon has anything to do with the wave length of the photon.
You can do the experiment yourself.
Don't depend too much on the authority.
Quote from: hamdani yusuf on 25/03/2024 09:21:59You can do the experiment yourself. So you couldn't find any citations that support your idea that the frequency of a photon's magnetic and electric fields somehow dictate it's size. Imagine my surprise.Quote from: hamdani yusuf on 25/03/2024 09:21:59Don't depend too much on the authority.Don't worry yourself, I don't. I suppose you don't go to the doctor when your sick because that would be appealing to authority? Why do you enjoy being complete confused about everything scientific?What I wrote about the nonexistent relationship between a photon size and it's wavelength is correct. I realize that if you accepted that it would decrease your confusion and I guess that would make you unhappy or something. Odd.
A photon doesn't have a size. It is a mathematical concept: an infinitesimal massless blob travelling at speed c with no other properties than energy and momentum.
But experiments clearly show that wavelength of EM waves determines their size of influence in space.
