Frequency Range of Radio Waves :
Radio waves boast the longest wavelengths within the electromagnetic spectrum. Their frequencies range from a low of 3 kHz (kilohertz) up to a high of 300 GHz (gigahertz). It's important to note that some classifications categorize frequencies above 3 GHz as microwaves.
This wide range of frequencies translates to a corresponding spread in wavelengths. At 3 kHz, the wavelength reaches a massive 100 kilometers, while at 300 GHz, it shrinks down to a mere millimeter!
