My initial thought is “no,” since our eyes, being receivers for specific wavelengths of EM radiation, can’t see frequencies like infrared, no matter how bright. Likewise, my cell phone’s WiFi and cell modules don’t conflict with each other (as far as this layperson can tell, anyway).
But if, for example, infrared were sufficiently bright/energetic, could it affect neighboring frequencies, like reds?
Thanks for the analogy! It’s pretty easy to understand how that works. I think I was imagining that EM waves shared some qualities with mechanical waves like sound, but I suppose that’s not the case!
