What is the sound produced by a radio set to AM when a flash camera, say, is charged beside it? When I charged a flash camera beside a radio set to AM, I noticed a series of sounds produced, similar to that of the harmonics of a sliding square waveform with frequencies above 16000 Hz. How do they interfere and what part of the camera generates radio waves?
