Frequently Asked Questions
-
What does one femtohertz represent?
-
One femtohertz corresponds to a frequency of 10^-15 hertz, which equals a cycle period of roughly 31.7 million years.
-
How is wavelength in terametres related to frequency in femtohertz?
-
Wavelength in terametres is calculated by dividing the speed of light by the frequency in femtohertz, translating extremely low frequencies into enormous spatial wavelengths.
-
Why use wavelength in terametres for these conversions?
-
Terametres allow expression of extremely long wavelengths, which are typical in astrophysical and gravitational wave studies involving interplanetary or larger distances.
Key Terminology
-
Femtohertz [fHz]
-
A unit of frequency equal to 10^-15 hertz, representing extremely slow oscillations with periods in the order of millions of years.
-
Wavelength in Terametres
-
The distance between successive wave crests expressed in terametres (10^12 meters), often used to describe very long wavelengths on cosmic scales.
-
Conversion Formula
-
The relationship λ = c / f where λ is wavelength, c is the speed of light, and f is frequency, used to compute wavelength from frequency.
