Discovered more than a century ago, the electromagnetic spectrum is the basis on which our universe operates. Without it we wouldn’t be able to see, stars wouldn’t shine, and life would not exist.

The strategy also noted that the DoD is transitioning from its definition that electronic warfare is separate from spectrum management to a more unified approach of electromagnetic spectrum operations ...

The electromagnetic spectrum is a rainbow of light waves that surround us — but we only see a small part of it. From radio waves to gamma rays, each type of light has its own properties and uses. By ...

On the other side of the spectrum, light with wavelengths slightly shorter than 380 nanometers is known as ultraviolet. Beyond that come X-rays and beyond that still come gamma rays.

The Defense Department Electromagnetic Spectrum Operations Cross Functional Team, which stood up in April, is leading the effort with the DOD's chief information office.

Unlike submillimeter waves, infrared light spans a vast range of the electromagnetic spectrum from 0.04 inches (just below 1 millimeter) on the side bordering with microwaves to 0.75 micrometers ...
