Each region of the electromagnetic spectrum has a range of wavelengths associated with it. The range of wavelengths affects the way each type of EM wave behaves and interacts with matter.

The core of the Phoenix cluster is shown across the whole electromagnetic spectrum. The bright purples represent X-rays produced by the hot gas, and the dashed purple outlines show regions where this ...

Terahertz (THz) technology refers to the use of electromagnetic waves in the terahertz (1 THz = 1012 Hz) region of the electromagnetic spectrum that covers the frequency range from roughly 0.1 to 50 ...

Researchers from Tokyo Metropolitan University have developed a new dye that can strongly absorb second near-IR radiation and transform it to heat. Starting with a dye from the bile pigment family, ...

The US Army is taking lessons from the war in Ukraine, where the battlefield has often been described as transparent. There's ...
