Shortwave: meaning, definitions and examples
📻
shortwave
[ ˈʃɔːrtweɪv ]
radio communication
Shortwave refers to a specific range of radio frequencies that are between 1.7 and 30 MHz. This band of frequencies is used primarily for long-distance communication, as shortwave radio waves can bounce off the ionosphere and travel over great distances. It is notably utilized for broadcasting, amateur radio, and two-way communication. Due to its ability to cover vast areas, shortwave radio is also important for international broadcasting and providing information in remote regions.
Synonyms
HF radio, high-frequency radio.
Examples of usage
- I listen to shortwave radio to catch international news.
- The ham operator uses shortwave frequencies to reach distant stations.
- Shortwave broadcasts can sometimes be interrupted by atmospheric conditions.

Etymology
The term 'shortwave' originated in the early 20th century as radio technology advanced. Originally, the term 'wave' was used to describe the propagation of electromagnetic radiation, and different bands of frequencies were discovered and categorized based on their wavelength and application. Shortwave frequencies were defined as those shorter than longwave (which are typically above 30 kHz). The properties of shortwave communication became evident during World War II, where it was utilized for military communication and espionage. Post-war, the technology became more widespread for broadcasting purposes, with stations using short wavelengths to reach audiences globally, including in remote areas where traditional broadcasting methods were ineffective.
