¶ Tunability
Index Entry
A wave is a principle. Discovering that we have waves which are tunable waves, which we will call the spectrum of light, and that we have waves of the air which we call sound, and other kinds of waves, there are tunable limits to what hear and then we get into infra and ultra sonic. We recognize then that we have a very small spectrum of tunability in respect to each one of our apprehending capabilities, Recognizing then that we have discovered this wave that operated in the phenomena water, milk or whatever it was, and yet was not a tunable wave. It was not in the spectrum of tunability, but yet we got information from it by what we call step-up or step-down transformations. Time and again as scientists we go through step-up and step-down frequencies and bring things into the audible range by relayings and stepping-up until finally we get the messages coming over the air, coming out of electromagnetic waves, and we put these together as familiar sounds.
