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?
The superposition principle says “no”.
What about if an em wave had enough energy to create a black hole 🤔
