A blast of radio waves from the outskirts of an ancient galaxy challenges theories about what creates such bursts.

THE recent discovery of solar radio noise, in the range ... we may expect that these changing fields will produce electromagnetic radiations the maximum wave-lengths of which are comparable ...

Electromagnetic radiation is the general term for the more familiar light and radio waves, but also includes gamma rays, x rays, ultraviolet rays, and infrared. All of these forms of electromagnetic ...

At the border between infrared and radio waves lie electromagnetic ripples measured in millimeters. They are now made in the laboratory, where they are used to study the properties of atoms and ...

THE electrical properties ... have always been of interest to the radio physicist and communication engineer, since the propagation of long and medium waves is markedly dependent upon the ...

Zimbabwean officials have backtracked on their show of support for an “inventor” who claimed to have found a way to create ...

All forms of electromagnetic radiation, whether they're called waves or rays, are generated by particles in motion. In a radio signal, for example, negatively charged electrons quickly move back ...

THz waves, located in the far-infrared region of the electromagnetic spectrum, can be used to perform non-invasive imaging through opaque materials for security and quality control applications.

What Is RADAR? Radio Detection and Ranging is a system or device that uses electromagnetic radio waves to determine the range, velocity, and angle of the objects in the surrounding area. This system ...
