Frequencies are measured in Hertz units and are commonly expressed in multiples (1000x) of that base. For Example: Hertz (Hz) => Kilohertz (kHz) => Megahertz (MHz) => Gigahertz (GHz) => …
Radio waves, infrared and visible light are all related b/c they operate along the same frequency spectrum.
|Radio Frequency Bands (Range):|
|AM Radio||~550-1720 kHz|
|FM Radio||~88-108 MHz|
Recall that: Hertz (Hz) => Kilohertz (kHz) => Megahertz (MHz) => Gigahertz (GHz) => …
So while the examples above can be expressed in any standard Hertz unit, the one you are used to seeing them with is generally more understandable.
WIFI: Used to seeing it listed as 2.4GHz or 5GHz. Keep in mind this is actually operating in a range like FM radio.Recall that 2.4Ghz = 2400MHz. Wifi specifically operates in the 2401MHz - 2495Mhz ranges. This range is subdivided into channels, similar to radio, it’s just that typically software handles the channel selection, …not something the average consumer generally modifies.
