long wave
Definition
Noun: A radio wave with a wavelength longer than 1000 meters (one kilometer), corresponding to a frequency below 300 kilohertz (kHz). This band of the radio spectrum is used for long-distance radio broadcasting and communication, especially in Europe.
Usage
"Long wave" refers specifically to a type of electromagnetic radiation used in radio transmission. It is used as a countable noun, often in the context of broadcasting bands or radio technology. - The station broadcasts on long wave. - Long wave signals can travel very long distances, especially over water or at night.

- Medium wave (MW) (n): The adjacent radio band with shorter wavelengths (typically 100-1000 meters).
- Short wave (SW) (n): The radio band with much shorter wavelengths (typically 10-100 meters).
Synonyms
- Low frequency (LF) radio wave: A more technical synonym, as the long wave band occupies the low-frequency part of the radio spectrum.
