Sublime

This involves, first, understanding powers of ten; second, visualizing data over a wide range of magnitudes on graphs using logarithmic scales; and third, appreciating the meaning of magnitude scales, such as the decibel (dB) scale for the loudness of sounds and the Richter scale for the strength of earthquakes.

We call the rate of fluctuation of the electromagnetic field its frequency, and we measure it with the unit called Hertz,

That’s just a parabola, the potential for a simple harmonic oscillator.

It’s “harmonic” when the potential is exactly proportional to x2

Frequency then, can be understood as a specific pattern of radiating energy, descriptive of its speed, type, or intensity of energy, perceivable or not perceivable.
