ClikeX originally claimed that the USSR had lasers in 1945 (untrue) and that Leon Theremin invented the detection of sound vibrations or audio reproduction of via light (also untrue).
The confusion here is between the two different eavesdropping systems developed by Theremin: The Buran eavesdropping system (which used likely-near infrared on windowpanes) and "The Thing" (which used VHF-UHF radio on a custom device).
Your repeated insistence on the unrelated point that "light" and "radio" are technically both electromagnetic waves isn't clarifying anything.
I'm quite confident it was an optical wavelength! ;)

Great summary!

I hope it's helped clarify that of the terms used here (light, radio, and electromagnetic waves) only "radio" is clearly distinct as "light" and "electromagnetic waves" are often synonyms.
This is an arbitrary restriction to the visible. (Note that the first person to mention the word "visible" was you!)
The original comment (ClikeX) clearly included radio waves in their intent, and that is an accepted definition! It's the definition I see used in practice as an optical engineer.
