What is a femtohertz?

A femtohertz is a unit of frequency equal to 10^-15 hertz, representing cycles per second with extremely low frequencies corresponding to very long periods.

How is wavelength related to frequency?

Wavelength is the spatial distance over which a wave's phase repeats and is inversely related to frequency based on the formula λ = v / f for wave speed v.

Why do wavelengths get so large at femtohertz frequencies?

Because femtohertz represents extremely low frequencies, the corresponding wavelengths extend to vast distances, often on the order of cosmological scales.
