Sentences with phrase «much shorter wavelengths»

On the other hand, the single CO vibrational band only absorbs IR at much shorter wavelengths (4.7 microns, or 2145 cm − 1), where the emission of radiant energy from Earth's surface is at least a factor of ten lower.

With much shorter wavelengths than photons of visible light, electron beams can be used to observe objects hundreds of times smaller than those that can be resolved with an optical microscope.

Scientists figured out more than a decade ago how to make this specialized form of light through a process known as «high harmonic generation,» or HHG, which shifts laser light to much shorter wavelengths and shorter pulses by shining it through a cloud of gas.

«Our proposed devices can retain the terahertz frequency like other terahertz sources but with a much shorter wavelength for an improved spatial resolution in imaging application as well as a very wide frequency tuning range from a microwave to a terahertz wave,» said Iurov.

Because electrons have a much shorter wavelength than visible light, they can illuminate the structure of tiny objects.

This unprecedented image of Herbig - Haro object HH 46/47 combines radio observations acquired with the Atacama Large Millimeter / submillimeter Array (ALMA) with much shorter wavelength visible light observations from ESO's New Technology Telescope (NTT).

Not exact matches

Short - wavelength light bounces back and forth between the ends of the guide, and the peaks and troughs of the counter-propagating light waves overlap to create a pattern of bright and dark bands much like the pressure patterns with a ringing organ pipe.

FOXSI detected a type of light called hard X-rays — whose wavelengths are much shorter than the light humans can see — which is a signature of extremely hot solar material, around 18 million degrees Fahrenheit.

Making metamaterials for shorter wavelengths such as visible light is more difficult because it entails making elements much smaller than a micron, approaching the sizes of components on modern computing chips.

And in the longer term, they could lead to bright, ultrafast, short - wavelength lasers that are much more compact, and perhaps even electronic devices that operate millions of times faster than current technology, says David Reis, a co-author of the report and deputy director of the Stanford PULSE Institute, a joint institute of SLAC and Stanford.

Its dishes collect wavelengths about a millimeter or less — much shorter than those detected by traditional radio telescopes.

We therefore need light that oscillates much faster, i.e. with shorter wavelengths.

But it takes the massive nucleus — think again of a cow, if you like — up to 1 million times more oomph to change its energy state and emit a photon that has a shorter wavelength and much higher energy.

Hard x-ray radiation is light with a wavelength in the range of picometers — much shorter than the wavelength of visible light.

Shorter wavelengths, such as blue light, are scattered much more than the longer ones.

Since it has been commissioned it has seen two major upgrades to further enhance its capabilities: addition of a second, blue arm optimized for shorter wavelengths of light; and the installation of detectors that are much more sensitive at the longest (red) wavelengths.

Because all variants except 3 × DVD and HD REC employed a blue laser with a shorter wavelength, HD DVD stored about 3.2 times as much data per layer as its predecessor (maximum capacity: 15 GB per layer compared to 4.7 GB per layer).

The surface area of these heaters can get quite hot and produce a relatively short infrared wavelength so will not offer as much benefit as a carbon based heater.

The stratosphere absorbs short wave (UV) radiation from the sun but is not hot enough to radiate much at short wavelengths.

That was before BEST broke out the scalpel and made the situation much worse from a long wavelength aspect by making short temperature segments fashionable.

When the Earth's temperature increases from 1 to 1 + p, the total radiation increases by a factor of (1 + p) ^ 4, Outgoing radiation increase at all wavelengths, but the PERCENTAGE increase at short wavelengths, which are not affected by CO2, increases at a much larger rate.

Shorter wavelengths though more energetic does not mean that they are therefore more powerful in penetrating matter, they are much weaker than the longer waves depending on the make up of the matter as more likely to get reflected and scattered because of their tiny size, and here, my point, is that the Solar energy balance graphic is wrong, because it has reversed the properties by giving Light energies the ability to penetrate and heat matter which is the actual, real, property of Thermal IR.

The CO2 molecules allow the shorter - wavelength rays from the Sun to enter the atmosphere and strike the Earth's surface, but they do not allow much of the long - wave radiation reradiated from the surface to escape into space.

Millimeter waves have greater speed capabilities because of their shorter signal wavelengths, broadcasting at much higher frequencies between 30 GHz and 300 GHz — a stark contrast to the current 3G and 4G signals that are broadcast below 6 GHz.
