American soldiers in the Indo-Pacific region are training to be "small and undetectable" in the electromagnetic spectrum.

But did you know that there's more to light than meets the eye? Let’s explore the amazing world of the electromagnetic spectrum! The electromagnetic spectrum has many types of light waves. It includes ...

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 ...

part of the electromagnetic spectrum. Like all waves, light’s nature is defined by its wavelength – the distance between two crests or troughs. At different wavelengths, it takes on different ...

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.

It's not easy to imagine how high the frequency of a high-energy gamma ray is. During the time it takes for its wave to go through one cycle, a gamma-ray wave traveling at the speed of light will ...

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 ...
