Radio: A radio basically captures radio waves which are transmitted by the radio stations. Radio waves can also be emitted by the gases as well as the stars in space. Radio waves are mainly used for the communication sector. The radio waves have the lowest frequenc...
Probing the speed of light with radio waves at extremely-low frequenciesMartin FullekrugAmerican Physical Society
ELF radio waves, the lowest of all radio frequencies, have a long range and are useful in penetrating water and rock for communication with submarines and inside mines and caves. The most powerful natural source of ELF/VLF waves is lightning, according to theStanford VLF Group. Waves produced...

DAB (Digital Audio Broadcasting) radio uses digital technology to transmit radio broadcasts, while FM is an analogue method that transmits audio over radio waves. DAB radio tends to sound cleaner as it is freer of interference and noise, while FM can be noisy due to overlapping frequencies. ...
Mobile frequencies are getting crowded with various applications like Music, Video on the Internet which intern requires more bandwidth. Need for Advanced Spectrum Management: Spectrum is regulated by governmental agencies. Spectrum access is granted by the regulatory agencies to the primary users or ...
Radio Astronomy is defined as the use of radio methods to study astronomy, utilizing the Earth's atmosphere to detect radio waves from celestial bodies within a specific wavelength range. AI generated definition based on: Big Data in Astronomy, 2020 ...
Cell phones operate at gigahertz frequencies, and so the antennas are small enough to hide inside the phone. But AM radio stations operate at much lower frequencies. For example, there’s a local station, KPRC, that broadcasts at 950 kHz, roughly one megahertz. That means the wavelength of...
The Amateur Radio Community Amateur radio, often referred to as “ham radio,” is a fascinating hobby that allows enthusiasts to communicate over long distances using radio waves. Operators experiment with antennas, frequencies, and modes, connecting with fellow hams worldwide. Beyond the technical ...
