Hmm. One could define DC to be a wave with zero frequency and most equations would work correctly. You often define a value at a singularity as a fixed value because that fixed value is approached as you get closer and closer. I personally have no problem thinking of a wave with zero amplitude.

- PhasmaFelis 11y agoHmm. Maybe. I think you can have a wave whose frequency is effectively zero for practical purposes, but in the most literal sense, a wave is defined by oscillation. In the case of EM in particular, I think the uncertainty principle says that a photon can't have zero energy, and thus can't have zero frequency (though it can be immeasurably low).
- kazagistar 11y agoHmm, I am not convinced. Photons are quantized, and there is a significant difference between a photon existing and not existing.
