Frequencies in the Hundreds of Hertz

The hectohertz (hHz) is a unit of frequency equal to 100 hertz (10² Hz), meaning 100 cycles occur every second. This frequency range is important in many areas including audio technology, engineering, and physics, where oscillations and waves in the low hundreds of cycles per second are commonly studied.

In audio and acoustics, frequencies around 100 Hz correspond to the lower bass range in human hearing. These sounds are fundamental to music, speech, and environmental noises, contributing to rhythm and tone. Subwoofers and bass instruments often operate in this range to produce deep, resonant sounds.

In engineering, hectohertz frequencies are significant for analyzing mechanical vibrations, structural resonances, and rotating machinery speeds. Monitoring and controlling vibrations in this range is essential for maintaining the safety and longevity of engines, bridges, and other infrastructure.

In physics and electronics, hectohertz frequencies can describe signals in communication devices, low-frequency radio transmissions, and various sensor outputs.

Understanding hectohertz frequencies helps scientists and engineers design better sound systems, improve mechanical performance, and develop technologies that rely on precise control and measurement of low-frequency waves.

A Quantum Limit of the Electron

The electron Compton wavelength is a fundamental constant in quantum physics that represents the limit at which the wave-like nature of an electron becomes significant in high-energy interactions. It is defined by the equation λ = h / (mₑ c), where h is Planck’s constant, mₑ is the mass of the electron, and c is the speed of light. The value of the electron Compton wavelength is approximately 2.426 × 10⁻¹² meters (or 2.426 picometers). This is significantly larger than the Compton wavelengths of heavier particles like the proton or neutron, reflecting the electron's much smaller mass.

The Compton wavelength is important because it sets a quantum limit on how precisely a particle's position can be defined without introducing enough energy to create particle-antiparticle pairs (like an electron and a positron). It plays a key role in quantum electrodynamics (QED), high-energy physics, and particle interactions involving photons and electrons. For instance, Compton scattering, a process where X-rays scatter off electrons, directly involves this wavelength. Understanding the electron’s Compton wavelength helps physicists analyze the structure of matter, radiation–matter interactions, and the behavior of particles at quantum scales.
