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 ...

The origin of these waves is unknown, but they promise to be useful in geophysics ...

yet it makes up just a small portion of the electromagnetic spectrum. We invite you to take this self-guided tour, which covers the spectrum from radio waves to gamma rays.

From the warm glow of the sun to audible radio waves and invisible gamma rays, electromagnetic waves (action between particles that have an electric charge) surround us. But did you know that there's ...

Trials have been completed on a new weapon system that directs a number of high-powered beams onto a single target.

This electromagnetic wave absorption and shielding material is less than 0.5mm thick and is distinguished by its low reflectance of less than 1% and high absorbance of over 99% across three ...

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 ...
