In radio, longwave (or long wave) refers to parts of the radio spectrum that has longer wavelengths. These are typically kilometer-sized or greater. The term is a historic one dating from the early 20th century. This was when the radio spectrum was considered to consist of long, medium and short wavelengths.
These waves have the longest wavelengths in the electromagnetic spectrum. They can range from thousands of metres to 30 cm. Radio waves are the lowest frequency waves in the EM spectrum. They can be used to carry other signals to receivers. Wi-Fi also uses radio waves that are routed through a wireless internet router.
Radio Waves. Radio waves have the longest wavelengths of all the electromagnetic waves. They range from around a foot long to several miles long. Radio waves are often used to transmit data and have been used for all sorts of applications including radio, satellites, radar, and computer networks. Microwaves.
Longwave. In radio, longwave, long wave or long-wave, [1] and commonly abbreviated LW, [2] refers to parts of the radio spectrum with wavelengths longer than what was originally called the medium-wave broadcasting band. The term is historic, dating from the early 20th century, when the radio spectrum was considered to consist of longwave (LW ...
Aug 10, 2016 · Credit: NRAO/AUI. Radio waves have the longest wavelengths in the electromagnetic spectrum. They range from the length of a football to larger than our planet. Heinrich Hertz proved the existence of radio waves in the late 1880s. He used a spark gap attached to an induction coil and a separate spark gap on a receiving antenna.

Oct 16, 2023 · Radio waves make up part of the electromagnetic spectrum. These waves are packets of energy with differing wavelengths, similar to visible light waves, X-rays or gamma rays, except longer. A radio wave, like other electromagnetic waves, is similar to an ocean wave or any other type of wave. Both types of wave have a hill and valley shape ...
The electromagnetic spectrum is comprised of all frequencies of electromagnetic radiation that propagate energy and travel through space in the form of waves. Longer wavelengths with lower frequencies make up the radio spectrum. Shorter wavelengths with higher frequencies make up the optical spectrum. The portion of the spectrum that we can see ...
