Frequently Asked Questions
-
What is a millihertz and when is it used?
-
A millihertz is a frequency unit equal to one-thousandth of a hertz, used to quantify very low-frequency oscillations encountered in fields like helioseismology, geophysics, and precision instrumentation.
-
What does wavelength in petametres represent?
-
Wavelength in petametres measures the distance between wave crests at extremely long scales, typically applied to astrophysical or cosmological wave phenomena spanning interstellar or intergalactic distances.
-
How is frequency related to wavelength in this conversion?
-
For electromagnetic waves, frequency and wavelength relate through the formula f = c/λ, assuming wave speed equals the speed of light.
Key Terminology
-
Millihertz (mHz)
-
A unit of frequency equal to one thousandth of a hertz, representing cycles per second at very low frequencies.
-
Wavelength in petametres
-
The spatial distance between successive crests of a wave, expressed in petametres (10^15 meters), useful for extremely long wavelength measurements.
-
Frequency-Wavelength Relation
-
The formula f = c/λ linking frequency (f) and wavelength (λ) assuming wave speed (c), typically the speed of light for electromagnetic waves.
