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 ...

These waves of energy are part of the electromagnetic spectrum that encompasses everything from long radio waves to very short gamma rays. Visible light, infrared radiation (heat), and ultraviolet (UV ...

Ultraviolet light has a shorter wavelength than visible violet light and infrared has a longer wavelength than visible red light. There are many wavelengths in the electromagnetic spectrum that we ...

Combining concepts from electromagnetic radiation research and fiber optics, researchers have created an extreme-ultraviolet, laser-like beam capable of producing tightly-focused light in a region ...

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 ...

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.

Frequency combs that operate in the ultraviolet regime allow for better spectroscopy than has been possible thus far, opening up a world of applications in atomic, molecular, and optical physics ...

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 ...
