Definition
Quantum frequency is the foundational QMU frequency. It is written \({F_q}\) and defined by photon velocity divided by Compton length:
Since \(\mathrm{velc}=c\), the SI bridge form is:
Propagation Anchor
The central QMU propagation identity is:
This states that a photon advances one Compton length per quantum moment. Quantum frequency supplies the rate; Compton length supplies the spatial step.
\({F_q}\) supplies the frequency or chronovibration rate.
\({\lambda_C}\) supplies the Compton-length quantum step.
Relation to Chronovibration
Chronovibration is the temporal standard or metronome of the Aether. Quantum frequency is the rate expression of that standard. It defines how quickly the Compton-length propagation step is repeated in the QMU foundation system.
Relation to Aether Rotational Closure
Quantum frequency also appears in the Aether rotational closure identity:
Since \(\mathrm{velc}=c\), this gives the SI bridge:
This connects quantum frequency not only to propagation, but also to rotational closure through the Aether unit and curl.
Relation to Magnetic Flux and Angular Momentum
Quantum frequency participates in QMU angular momentum through the four-letter unit \(\mathrm{angm}\). In QMU-first notation, angular momentum is:
The SI bridge for the same quantity is Planck's constant:
Since magnetic flux can be written as \(\mathrm{mflx}=\mathrm{angm}/{e_{emax}}^{2}\), quantum frequency also participates in magnetic-flux structure:
APM / QMU Role
Quantum frequency is one of the essential QMU foundations. It anchors time, velocity, acceleration, resonance, radiation, QMU angular momentum \(\mathrm{angm}\), magnetic flux, energy, and propagation closure. It is the frequency side of the length-frequency pair that gives photon velocity.
Research Use
Quantum frequency is a high-value research node because every time-bearing QMU expression traces through \({F_q}\). Useful directions include tracing every occurrence of \({F_q}\) in the QMU inventory, comparing positive and negative frequency powers, studying the \({F_q}{\lambda_C}=\mathrm{velc}\) propagation identity, and mapping how \({F_q}\) enters QMU angular momentum \(\mathrm{angm}\) and magnetic flux.
