Here’s how it works. Different wavelength of the electromagnetic spectrum reveal different aspects of the universe. (Image credit: Space Telescope Science Institute) ...

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 outer shell contains pure silver, blocking radio waves and microwaves across a frequency range of 0.2GHz to 10GHz. This technological spectrum covers Wi-Fi, Bluetooth, satellite communications ...

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.

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 ...

Humans can see a range of light waves called the visible light spectrum, which encompasses wavelengths from around 380 to 700 nanometres. The contact lens technology uses nanoparticles that absorb ...

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 ...

Imec, Ghent University and the Max Planck Institute in Garching have realised a frequency comb light source in the mid-IR wavelength band. These frequency comb light sources with an extended spectrum ...

Light of shorter or longer wavelengths doesn't excite our eyes' receptors — so we can't see anything beyond red (infrared) or violet (ultraviolet) on the electromagnetic spectrum of light.

Infrared radiation is energy that we feel as heat. It is in the spectrum just below the energy that can be seen with the naked eye, but is a higher-frequency wavelength than microwaves.

Laser frequency combs, sources with a spectrum consisting of hundred thousands evenly spaced narrow lines, have an exhilarating potential for new approaches to molecular spectroscopy and sensing ...
