Electron Frequency

Electromagnetic Spectrum

Wiki’s electromagnetic spectrum table shows a range from extremely low frequency 3 Hz to Gamma rays at 300 EHz. The RF (radio frequency) part of the same spectrum spans frequencies from extremely low RF, 3 Hz to extremely high RF, 300 GHz. Beyond the high frequency RF at 300 GHz is a range from the far infrared 3 THz to Gamma rays 300 EHz. The visible light range is within the 300 THz to 3 PHz range designated as near infrared to near ultraviolet.

Note: Wiki: “Hertz (Cycles per second) are commonly expressed in multiples (of 1,000): kilohertz (kHz), megahertz (MHz), gigahertz (GHz), terahertz (THz), petahertz (PHz), and exahertz (EHz).” https://en.wikipedia.org/wiki/Hertz

Frequency ?    Representation of the electric field vector of a wave of circularly polarized electromagnetic radiation. But what is its frequency? https://en.wikipedia.org/wiki/Electromagnetism#History_of_the_theory

The near ultraviolet, extreme ultraviolet, soft X-rays, hard X-rays and gamma rays are all natural frequencies but the RF part of the spectrum consists mainly of artificially generated frequencies – radio transmissions – although some may be found to be occurring naturally due to various natural modulations. The point of all this is that we are not seeing natural frequencies in the RF radio spectrum, radio waves are generated by electricity and tuned with a tuner.

The various radio frequencies listed in the spectrum are tuned to their specific frequencies by a radio frequency tuner unlike other EM frequencies (like light) that are resonating at their natural frequency. The natural frequency of a radio wave is never given and we are not told why.

Natural frequency
Wiki:Natural frequency, also known as eigenfrequency, is the frequency at which a system tends to oscillate in the absence of any driving or damping force.”  (This is entirely absent in the case of radio frequency.)

In other words a frequency that is not a natural frequency has to be driven artificially. Therefore all of the radio frequencies in the spectrum are artificial, the product of intentional human design and manufacture.
There are exceptions, radio telescopes detect stellar radio frequencies in the GHz microwave band called radio frequencies but these have different properties associated with heat.

According to Wiki: “A tuner is a subsystem that receives radio frequency (RF) transmissions like radio broadcasts and converts the selected carrier frequency and its associated bandwidth into a fixed frequency that is suitable for further processing, usually because a lower frequency is used on the output… …some of the earlier types were purely mechanical and adjusted the capacitance or inductance of the tuned circuit to a preset number of positions corresponding to the frequencies of popular local stations” https://en.wikipedia.org/wiki/Tuner_(radio)
No mention of how a tuner works because the Wiki editor probably does not know how it works.

crystal tuner
The most basic crystal set tuner, the pattern for all tuners that came after.

Wiki’s “tuner is a subsystem” is grossly misleading as in the case of a receiver it is the radio tuner that sorts-out all transmitted frequency in-puts from the antenna. In the case of a transmitter it decides the wavelength of the transmitted signal. The tuner is the most important part of any radio transmitter or receiver be it radio, Wi Fi or TV. The original radio receivers had only a tuner and a detector. No radio receiver can ever work without a tuner.

Frequency of an Electron
Suppose we want to find the natural frequency of an electron, (it is oscillating it has vibrations) where do we look on the spectrum? No one seems to know. Try Googling “frequency of an electron”? If, as we are told electricity occurs in waves and waves can only be waves if they have a frequency, then what is the frequency of an electron or a DC current in a conductor? We are looking for the natural frequency. Missing

Particle–wave duality is a central tenet of quantum physics, and an electron
has wave-like properties. Introductory texts discuss the wavelength–momen-
tum relationship l = h p , but do not discuss the frequency–energy relation-
ship. This is curious since a wave is periodic both in space and time (oscillating- undulating).

The discussion in more advanced texts is not satisfactory either since two different
expressions for the frequency are given based on the relativistic and non-
relativistic expression for the electron energy. The relativistic expression
yields the correct frequency, and we explain why the expression based on the
Schrödinger equation gives the incorrect expression. We argue that the elec-
tron frequency should be discussed at the introductory level.

The writer is obviously not happy and that is as close to an answer as you are likely to get/or not.

What is the frequency of a DC current in a conductor?
When we consider that electricity has to be a wave – we are told that an electron is a wave and so we expect a wave to have a frequency. Science dodges this one by insisting that electrons have a range of frequencies. OK, what is the combined or average frequency of an electron? You will not get a straight answer because no one has an answer.

I don’t think that anyone who even attempted to answer really understood the question. Check for yourself: many answers insist on modulating the DC and then measuring the frequency – which is absurd. This is to highlight the complete confusion encountered when awkward electrical questions are asked, a confusion that is deliberate and intended to confuse the student. It is not possible to find the frequency of something that does not exist.

We have an electromagnetic spectrum that does not include natural electricity. If anyone has the answer to this let me know.
