Frequently Asked Questions
-
What is the picohertz unit used for?
-
Picohertz measures extremely low frequencies corresponding to cycles occurring over millions of years, useful in geophysical and astrophysical studies of long-term periodic phenomena.
-
Why convert wavelength in millimetres to picohertz?
-
Converting wavelength to picohertz helps translate physical wave distances into ultra-low frequency values, allowing analysis across vastly different time and frequency scales relevant to various scientific fields.
-
Can I use this conversion for typical wireless communication frequencies?
-
No, this conversion is not practical for normal electromagnetic wave applications like communication or radar that involve much higher frequencies and shorter wavelengths.
Key Terminology
-
Wavelength in millimetres [mm]
-
The physical distance between successive wave peaks measured in millimetres; often used for electromagnetic waves where wavelength relates inversely to frequency.
-
Picohertz [pHz]
-
A unit of frequency equal to 10^-12 hertz representing cycles occurring over trillions of seconds, used for describing ultra-low frequency oscillations.
-
Millimetre-wave (mmWave)
-
Electromagnetic waves with wavelengths roughly from 1 to 10 millimetres, commonly employed in high-frequency communication systems and radar.
