Physicists have created the first "frequency comb" in the extreme ultraviolet band of the spectrum, high-energy light less than 100 nanometers in wavelength. Laser-generated frequency combs are ...

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.

UV radiation is a part of something that you may faintly remember from your K-12 or collegiate years called the electromagnetic spectrum (below). Electromagnetic energy propagates in wave form and ...

UV light has a shorter wavelength than visible light, which has a shorter wavelength than infrared radiation. The full electromagnetic spectrum. Credit: NASA’s Imagine the Universe It takes about 8 ...

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 ...

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.

Following the discovery of new regions of the electromagnetic spectrum such as ultraviolet (UV) and X-ray radiation, refractive lenses were developed that are specifically adapted to these ...

Dogs and cats are able to see into the ultraviolet part of the electromagnetic spectrum. This allows the animals to see in wavelengths invisible to the human eye.

Researchers last year discovered that dogs, cats and some other mammals can see more than humans. They can see into the ultraviolet part of the electromagnetic spectrum, which allows them to see ...
