Hogerfrequentie

Hogerfrequentie, a Dutch term, translates to "high frequency" in English. It generally refers to electromagnetic waves or electrical signals that operate within a range of frequencies considered higher than those used for standard audio or power transmission. In the context of radio waves, high frequency typically encompasses the band from 3 to 30 megahertz (MHz). This portion of the radio spectrum is known for its ability to propagate over long distances by reflecting off the ionosphere, a phenomenon known as skywave propagation.

This characteristic makes high frequency bands crucial for long-range communication, particularly for amateur radio operators, shortwave broadcasting, and certain military and aviation applications. Beyond radio, the term "hogerfrequentie" can also be applied to electrical currents in industrial processes, such as induction heating, or in medical applications like diathermy. The specific meaning and range of frequencies associated with "hogerfrequentie" can vary depending on the particular field or application being discussed. Understanding the context is key to precisely defining what constitutes a high frequency.
