Scientists may be just 15 years away from finally detecting dark matter thanks to a new kind of detector that acts like a “cosmic car radio.” Designed to pick up the elusive frequency of axions — hypo ...

For over a decade, a contentious policy struggle has simmered in the United States over the allocation of radio spectrum — a ...

Published in Nature, scientists at King's College London, Harvard University, UC Berkeley and others have shared the ...

The electromagnetic spectrum has many types of light waves. It includes radio waves, microwaves, infrared light, visible light, ultraviolet, X-rays, and gamma rays. Each type of light has a different ...

The EA-18G Growler is the U.S. Navy’s premier electronic warfare (EW) aircraft, built to suppress enemy air defenses and ...

The types of radiation that occur in different parts of the spectrum have different uses and dangers - depending on their wavelength and frequency. The speed of electromagnetic waves in a vacuum ...

region of the electromagnetic spectrum that covers the frequency range from roughly 0.1 to 50 THz. Terahertz electromagnetic waves occupy a middle ground between electronics waves, like microwave and ...

Electromagnetic radiation is the general term for ... and lower (moving away) frequencies. The resulting spectrum (power vs. frequency) shows two peaks. These features are very narrow compared to most ...
