Sometimes a division by wavelength is used: Short wave (SW): Wavelengths of 10-200m hence frequencies of 1.5-33 MHz ; there are several sub-bands. Medium wave (MW): Wavelengths of 200-1000m hence frequencies of 300 kHz-1.5 MHz. Long wave (LW): Wavelengths > 1000m hence frequencies < 300 kHz.

The name “shortwave” originated during the beginning of radio in the early 20th century, when the radio spectrum was divided into long wave (LW), medium wave (MW), and short wave (SW) bands based on the length of the wave .
Read moreWhat is MW frequency?
Medium wave (MW) is the part of the medium frequency (MF) radio band used mainly for AM radio broadcasting . The spectrum provides about 120 channels with more limited sound quality than FM stations on the FM broadcast band.

The tone of lowest frequency is called the fundamental ; the others, overtones. The frequencies of the overtones may be whole multiples (e.g., 2, 3, 4, etc., of the fundamental frequency, in which case they…
Read moreWhat is very low frequency used for?
The VLF band is used for a few radio navigation services, government time radio stations (broadcasting time signals to set radio clocks) and for secure military communication . Since VLF waves can penetrate at least 40 meters (131 ft) into saltwater, they are used for military communication with submarines.
Read moreWhat are very low frequency waves?
Very low frequency (VLF) is a radio frequency band in the range of 3 to 30 kHz with wavelengths from 10 to 100 km . It is also the name of the band designated by the International Telecommunication Union (ITU).
