Light is produced and consumed in quanta (photons) by reguar matter. Light itself is just radio wave. Radiowave has not such limitation. It's limitation of atomic particles.
That's not how quantum mechanics works. Radio waves are photons, and photons are radio waves. Different experiments will reveal different aspects of it, but these are not separate phenomena.
Also, the exact same thing is true of every other particle: just as photons are quantizations of the electro-magnetic waves, electrons are quantizations of waves in the electron field, quarks are quantized waves in the quark field etc. Atoms and molecules are also waves; in fact, there have been experiments showing the wave-like nature of molecules with something like 5000 atoms.
I saw water-like behavior of a wave! I have no idea, how much molecules it contains, large waves have many cubic meters of water, but I'm pretty sure that quantum behavior is not limited to 5000 atoms. Waves, even very large onses, are moving energy in "packets". 1 wave - 1 quanta. So, what?
Photon is radio-wave (EM-wave). Typical photon is produced and consumed by a electron, so properties of photon produced by an electron are limited by the electron, also, our abilty to detect photonare limited by the electron. However, EM-waves in general are not limited by electron.
On smaller scale, electron interacts with other charged particles and with EM-field (the medium) via EM-waves. I'm pretty sure that electron is not staying stil, it's vibrating because of thermal noise. Vibration of charged particle produces EM-waves. Those EM-waves are not photons.
> Vibration of charged particle produces EM-waves. Those EM-waves are not photons.
Yes, they are. In the Standard Model, the photon is the "carrier" particle of the EM field. Any EM interaction between any two charged particles is ultimately the exchange of one or more photons between those two charged particles. When a particle emits an EM wave, in any way, it emits one or more photons. It's impossible to emit 1/2 a photon or 1.3 photons - the EM field / EM waves come in quantities of whole photons.
In the same way, when two quarks interact via the strong interaction, they are emitting and absorbing gluons, the carrier particle of the strong force.
The only fundamental interaction not currently proven to be quantized is gravity. We do know gravity waves exist, but we have not been able to measure them to the required fidelity to verify whether they are also quantized, and thus to know whether they are also equivalent to an exchange of particles (we call these hypothetical particles gravitons, and many do believe that gravitational interactions also occur by the exchange of a whole number of gravitons between bodies with "gravitational charge", i.e. mass).
Unlike regular waves, photons are topologically stable, like smoke-ring kind of wave. Google hopfions for example.
If you like hydrodynamic quantum analogs (walking droplets), then you may see that droplet may escape it pilot wave sometimes. In such cases, pilot wave continue to travel in same direction for some time. IMHO, it's similar to how photons are formed: electron creates pilot wave, then escapes it, similar to Cherenkov radiation.
Anyway, photons have special configuration, so they behaves differently than regular waves.
Gravitational waves, AFAIK, are not topologically stable at all.
