For water waves and sound waves the unit hertz is usually good enough but radio and TV waves have such a high frequency that the kilohertz (\(kHz\)) or even the megahertz (\(MHz\)) are better units.

The Biomass mission will use a long-forbidden part of the radio spectrum to see how much carbon forests capture.

AMONG the facts to be explained in a satisfactory theory of the propagation of radio waves over the earth's surface are the curvature of the rays in transmission between stations far apart ...

A Ham radio operator will ... distance proportional to the wavelength. For me personally, this was a real eye-opener. Now I not only understand where the standing waves come from, but that the ...

There are seven types of electromagnetic (EM) waves, which make up the electromagnetic spectrum. Electromagnetic waves are transverse waves, and travel at the speed of light. Different types of ...

European astronomers have carried out multi-wavelength radio observations of a radio galaxy designated 3C 111. Results of the observational campaign, published March 24 on the arXiv preprint server, ...

We have recently succeeded in detecting the diffraction pattern of radio waves scattered from the electron trail as a meteor passes at right angles through the aerial beam. These observations lead ...

Some atoms and molecules in space emit radio waves at particular frequencies. Hydrogen atoms emit at 1420 MHz (a wavelength of 21 cm). Hydroxyl molecules, composed of one atom of hydrogen and one atom ...

A powerful X1.1-class solar flare was released by the sun on March 28, resulting in radio blackouts across North and South America ...

What makes this radio signal special is that it’s at a specific wavelength known as the ... pulsars – and often emit bursts ...

All forms of electromagnetic radiation, whether they're called waves or rays, are generated by particles in motion. In a radio signal ... is characterized by wavelength (the distance from the ...

The radio telescope at the Algonquin Radio Observatory, located in Algonquin Park, Ontario, is typical of the radio ...
