Reply to comment by mckulty in Do photons of different wavelengths combine to make complex wave forms? by Max-Phallus

I understand what harmonics are. I couldn’t figure out what point you were making.

But the original question was about radio waves, which are not visible light.

So I still don’t understand why you’re making the argument that it’s impossible to have a photon at one frequency and then another photon at 2x that frequency, just because they wouldn’t both be in the range our eyes can see.
