Frequently Asked Questions
-
What does converting wavelength in millimetres to nanohertz represent?
-
It translates the spatial distance between wave crests into an extremely low frequency, showing how millimetre-scale waves relate to phenomena with very long periods.
-
Can this tool be used for waves in media other than vacuum?
-
No, the conversion assumes vacuum propagation and does not account for effects from other media that may change wavelength or frequency.
-
Why are nanohertz frequencies important for scientific studies?
-
They describe very slow processes such as gravitational waves detected over years, long-term solar activity cycles, and slow geophysical changes.
Key Terminology
-
Wavelength in millimetres [mm]
-
The physical distance between successive wave crests measured in millimetres, typically ranging from 1 to 10 mm for millimetre waves.
-
Nanohertz [nHz]
-
A unit of frequency equal to 10⁻⁹ hertz, used to characterize extremely low frequencies corresponding to very long periods.
-
Millimetre-wave (mmWave)
-
Electromagnetic waves with wavelengths approximately between 1 and 10 millimetres, often used in wireless communications and radar.
