Radio waves are detected using electrical circuits that receive these electromagnetic signals in an antenna, and then the radio frequencies are modulated through capacitors before emerging as sound in a speaker. Radio waves are normally less than a kilohertz long up to 20 gigahertz.

A radio tuner receives radio waves and converts them to mechanical vibrations in the speaker to create sound waves that can be heard. Radio waves are a type of electromagnetic radiation best-known ...

They came from outer space. More “fast radio bursts" – bright, short-lived pulses of radio waves that come from across the universe – have been detected by astronomers. The bursts, which ...

en.wikipedia.org/wiki/Detector_(radio)

In radio, a detector is a device or circuit that extracts information from a modulated radio frequency current or voltage. The term dates from the first three decades of radio (1888-1918). Unlike modern radio stations which transmit sound (an audio signal) on an uninterrupted carrier wave, early radio stations transmitted information by radiotelegraphy.

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 surface wave or any other type of wave. Both types of wave have a hill and valley shape, repeating over and over.

CHIME was designed to detect ancient radio waves sent out when the universe was just a toddler, some 6 billion to 11 billion years ago. Though it has been in operation for only about a year, it ...

A huge Russian telescope in a remote part of the Caucasus detects a mysterious burst of radio signal coming from far away in outer space. It’s traced to a 6.3 billion-year-old star in a ...

Off its rocky surface, the Moon reflects radio waves emitted by our home galaxy, the Milky Way. And now astronomers have detected them. The signal was picked up by researchers from the Curtin University node of the International Centre for Radio Astronomy Research (ICRAR) and the ARC Centre of Excellence for All Sky Astrophysics in 3 Dimensions (ASTRO 3D).

“[We now know] the sources can produce low-frequency radio waves and those low-frequency waves can escape their environment, and are not too scattered to be detected by the time they reach the ...
