radiofrekvente
Radiofrekvente, also known as radio frequencies, are a type of electromagnetic radiation with wavelengths in the electromagnetic spectrum longer than those of microwaves and shorter than those of infrared light. They are used for various purposes, including communication, broadcasting, and navigation. Radiofrekvente are typically measured in Hertz (Hz), with the range extending from 3 kHz to 300 GHz. This range is further divided into several bands, each with specific applications and regulations.
The lowest frequency band, known as the Extremely Low Frequency (ELF) band, ranges from 3 Hz to
The Medium Frequency (MF) band, ranging from 300 kHz to 3 MHz, is used for AM radio
The Super High Frequency (SHF) band, ranging from 3 GHz to 30 GHz, is used for satellite
