-
Results may vary for different media or wave types where this assumption fails.
-
Measurement of extremely low frequencies can be difficult due to instrumental precision constraints.
Frequently Asked Questions
-
What does wavelength in gigametres represent?
-
It is the spatial period of a wave measured in gigametres, describing distances between corresponding wave points such as peaks, where 1 Gm equals 10⁹ metres.
-
What is a microhertz [µHz]?
-
A microhertz is a frequency unit equal to one millionth of a hertz, used to quantify extremely low-frequency or long-period oscillations.
-
Why is this conversion useful?
-
It relates large spatial wave scales to their corresponding frequencies, aiding analysis in fields like astrophysics, space plasma physics, and geophysics.
