Shortwave

Shortwave radio operates between the frequencies of 3,000 kHz and 30 MHz (30,000 kHz) and came to be referred to as such in the early days of radio because the wavelengths associated with this frequency range were shorter than those commonly in use at that time. An alternate name is HF, or high frequency.

Short wavelengths are associated with high frequencies because there is an inverse relationship between frequency and wavelength.
