MEDIUMWAVE Meaning and
Definition
-
Mediumwave refers to a form of radio broadcast transmission that operates within the frequency range of the electromagnetic spectrum typically spanning from about 530 kilohertz (kHz) to 1,710 kHz. Also known as AM (Amplitude Modulation) radio, mediumwave is characterized by its ability to transmit radio signals over relatively long distances due to its ability to bounce off the Earth's ionosphere layers.
Mediumwave frequencies were historically an integral part of radio broadcasting, serving as a prominent means of disseminating news, entertainment, and cultural content. However, with the emergence of FM (Frequency Modulation) radio and digital audio broadcasting, the popularity and usage of mediumwave have diminished considerably in some regions.
The term "mediumwave" originated from the concept that these frequencies occupy an intermediary position between longwave frequencies (below mediumwave) and shortwave frequencies (above mediumwave) in the radio wave spectrum. Due to its longer wavelength compared to higher frequency bands, mediumwave can efficiently penetrate obstacles like buildings and hills, making it relatively reliable for regional or local radio broadcasting.
Mediumwave broadcasts are typically received using relatively simple receivers commonly known as AM radios. These radios employ an antenna to capture the mediumwave signals, which are then amplified and demodulated to retrieve the original audio content. Mediumwave radio stations typically employ towers and transmitters to broadcast their signals, covering a target geographic area through a combination of ground wave propagation and skywave (ionospheric) propagation.
Etymology of MEDIUMWAVE
The word "mediumwave" is a compound word derived from the combination of the terms "medium" and "wave".
The term "medium" originated from the Latin word "medius", meaning "middle" or "midway". In the context of "mediumwave", the word refers to the wavelength range in between the longer "longwave" and shorter "shortwave" frequencies used in radio communication.
The term "wave" can be traced back to the Old English word "wæg", which indicated the movement or undulation of water or similar substances. In the context of radio waves, it refers to the transmission of energy in waves through the air and other mediums to carry radio signals.
Therefore, "mediumwave" essentially refers to the specific range of radio frequencies in the middle range between longwave and shortwave.
