Key Terminology
-
Wavelength in metres [m]
-
The spatial distance over which a periodic wave's phase repeats, measured in metres.
-
Wavelength in millimetres [mm]
-
The physical distance between wave crests measured in millimetres; 1 mm equals 10⁻³ metres.
-
Millimetre-wave (mmWave)
-
A range of electromagnetic waves with wavelengths approximately between 1 mm and 10 mm, used in high-frequency wireless systems.
