Femtohertz

fHz

Definition

The Femtohertz is a unit of frequency equal to 10^-15 hertz, representing frequencies in the extremely low sub-audio range. It corresponds to wavelengths in the hundreds of quintillions of kilometers range and is used in scientific instruments, low-frequency oscillators, and specialized measurement applications.

History/Origin

The femtohertz unit was established as part of the SI system to provide intermediate frequency measurements between the base hertz and smaller frequency units. It represents frequencies that are 15 orders of magnitude lower than the base hertz unit, corresponding to wavelengths in the extremely long-wave radio region.

Current Use

Used in scientific instruments, low-frequency oscillators, and specialized measurement applications. It is particularly useful for measuring frequencies in the extremely low sub-audio range and for understanding the behavior of systems that operate at extremely low frequencies.
