This was my first thought. I imagined a steeple but how would that mean any sort of diagnosis? Simply: it wouldn't.
Besides the latest research on autism defines it as a hugely vast spectrum. So vast that I thought many were thinking everyone is technically on the spectrum.
I'd say it still starts at zero, even if the zero itself doesn't correspond to anything physical. Everything not quite zero still corresponds to something that may actually exist. mHz (small m) radio waves are real things.

Good point. Zero stones don't physically exist. That is why it took so long for cultures to include zero as a number. I read an entire book about zero (and one each about pi, e, infinity, and sqrt(-1)).
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.
Hmm. 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).
We're not talking about AC frequencies here. Electromagnetic waves are different. The only 0-frequency EM wave is literally "no wave". Nothing happening.
For one, it only tests what people say and they answer only what they think they were thought. Secondly, imagining an image doesn't preclude parallel abstract thought.
