"Microwave" is the official label for radio between 3 GHz and 300 GHz. That frequency range corresponds to wavelengths from 1 millimeter to 10 centimeters.
Radio waves have a frequency range that typically spans from about 3 kHz (kilohertz) to 300 GHz (gigahertz). The minimum frequency of 3 kHz corresponds to the very low frequency (VLF) range, while the maximum frequency of 300 GHz falls within the extremely high frequency (EHF) range. This broad spectrum allows radio waves to be utilized for various communication technologies, including AM and FM radio, television, and wireless networks.
Infrared radiation is much higher frequency (300 GHz to 430 THz) than the VHF and UHF bands (30 MHz to 3 GHz) frequencies used by broadcast TV.
The frequency of x-ray in the range 30 petahertzto 30 exahertz (3 × 1016 Hz to 3 × 1019 Hz) and
3 - 30 megahertz is a frequency range within the radio frequency spectrum, commonly used for radio broadcasting, television broadcasts, and various communication systems. It falls in the low frequency range compared to higher frequency bands like microwaves or infrared.
Wavelength = (speed) divided by (frequency)= (3 x 108) / (3 x 109) = 0.1 meter = 10 centimeters
Human beings generate, transmit, and receive radio waves, for various purposes,in the range of roughly 60 KHz to 300 GHz.There is a system of formal designation of radio, corresponding to decades (10 times)of frequency/wavelength. You'll recognize some of the abbreviations, like VHF and UHF:Very Low Frequency (VLF)3 - 30 KHz100,000 - 10,000 metersLow Frequency (LF)30 - 300 KHz10,000 - 1,000 metersMedium Frequency (MF)300 KHz - 3 MHz1,000 - 100 metersHigh Frequency (HF)3 - 30 MHz100 - 10 metersVery High Frequency (VHF)30 - 300 MHz10 - 1 meterUltra High Frequency (UHF)300 MHz - 3 GHz1 meter - 10 cmSuper High Frequency (SHF)3 - 30 GHz10 - 1 cmExtreme High Frequency (EHF)30 - 300 GHz1 cm - 1 mm
The frequency range reserved for radio waves is typically below 3 kHz, while the microwave frequency range starts from about 300 MHz (not kHz) and extends to 300 GHz. Within this range, different applications and technologies utilize specific frequency bands to ensure efficient and interference-free communication.
