   What about resonance and harmonics? A receptor set at a certain
frequency will resonate only at that frequency regardless of the
intensity of the incoming waves. Once the waves are the right
frequency and reach minimum intensity needed to overcome the inertia
of the receptor, the receptor will resonate and give off its own
waves. It seems to me that is a more sensible explanation than
claiming that matter, in the sense of some solid particle, possesses a
property resembling "frequency."
