Frequently Asked Questions
-
What does wavelength in dekametres represent?
-
It represents the spatial period of a wave, the distance between successive identical points, expressed in dekametres where 1 dekametre equals 10 metres.
-
What is a femtohertz?
-
A femtohertz is a unit of frequency equal to 10^-15 hertz, indicating extremely slow oscillations with periods spanning millions of years.
-
Why convert between wavelength in dekametres and femtohertz?
-
Converting relates familiar wavelength scales for radio or antenna design to very low frequencies useful in geophysical and cosmological research.
