The Unit for Slow Oscillations

The centihertz (cHz) is a unit of frequency equal to 10⁻² hertz, meaning one cycle occurs every 100 seconds, or approximately 1 minute and 40 seconds. This frequency range is useful in studying slow, periodic phenomena in fields like geophysics, astrophysics, and engineering.

In geophysics, centihertz frequencies often describe slow seismic waves and Earth’s natural resonances after earthquakes. These oscillations provide insights into the planet’s interior structure and the behavior of seismic waves as they travel through different layers. Monitoring these frequencies helps improve earthquake understanding and early-warning systems.

In astrophysics, centihertz frequencies correspond to certain pulsations in stars and compact objects like neutron stars. These slow oscillations help scientists probe the physical properties, rotation, and magnetic fields of such objects.

In engineering, centihertz vibrations may be important for studying the stability and resonance of large structures like bridges or skyscrapers, which can oscillate slowly under environmental forces like wind or traffic.

Centihertz frequencies represent a middle ground between very slow ultra-low frequencies and faster oscillations. By understanding these frequencies, researchers can better analyze processes that unfold over minutes, bridging time scales relevant to both natural phenomena and engineered systems.

The Vastest Scales of Cosmic Waves

An exametre (Em) is equal to 1,000 petametres (10¹⁸ metres), representing one of the largest units of length used to describe the longest electromagnetic wavelengths and gravitational waves in the universe. At this scale, wavelengths correspond to frequencies in the zeptohertz (10⁻²¹ Hz) range and lower, which are incredibly slow oscillations occurring over billions of years and spanning distances larger than entire galaxy superclusters.

For example, waves with a frequency of around 1 zeptohertz have wavelengths on the order of 300 exametres. These enormous waves are primarily theoretical and are significant in cosmology and astrophysics for studying the large-scale structure of the universe, primordial fluctuations from the Big Bang, and the behavior of space-time itself.

Using exametres to express wavelength helps scientists conceptualize the almost incomprehensible vastness of the cosmos. These extreme wavelengths provide key insights into the fundamental nature of the universe, including gravitational wave backgrounds and the evolution of cosmic structures on the grandest scales.
