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 ...

Waves in the electromagnetic spectrum can all travel through a vacuum at the speed of light. The wide range of frequencies and wavelengths of different waves have a variety of uses.

On the other hand, optical fibers use light, lying at an even higher frequency range in the electromagnetic spectrum (roughly between 430 THz - 790 THz), to carry information.

Spectrum Connect, a family of handheld spectrum analyzers from SAF Tehnika, now offers a version with a frequency range of 10 MHz to 3000 MHz. The lineup comprises seven handheld spectrum analyzers ...

The Sun emits electromagnetic radiation across a broad spectrum, including visible, infrared, microwave, radio, ultraviolet, X-ray, and gamma-ray wavelengths. Visible light, comprising wavelengths ...

Telescope mirror coatings (e.g., silver, gold, aluminum) determine which wavelengths of light are reflected. X-ray telescopes use specially shaped mirrors to reflect X-rays, which are normally ...

The newest generation of cellphones, 5G, will operate near the highest frequencies of the radio wave spectrum. Lower down in the spectrum are wireless networks used in homes and schools ...

Learn about the electromagnetic spectrum, the order of the waves, their uses and dangers with this guide for KS3 physics students aged 11-14 from BBC Bitesize.
