Sentences with phrase «infrared energy through»

Not exact matches

The mirrors allow visible light to pass through, but they reflect infrared light back to the emitter, where it's absorbed and some of the energy is re-emitted as visible light.

Now researchers at the Department of Energy's SLAC National Accelerator Laboratory, Stanford University and Louisiana State University have achieved an even more dramatic HHG shift by shining an infrared laser through argon gas that's been frozen into a thin, fragile solid whose atoms barely cling to each other.

«Observations at different wavelengths across the infrared spectrum allow us to piece together a three dimensional picture of how energy and material are transported upwards through the atmosphere.»

Another trick is to design a photovoltaic cell that allows visible light to pass through while collecting energy from infrared and ultraviolet radiation.

To passively cool the solar cells, allowing them to give off excess heat without spending energy doing so, requires exploiting the basic properties of light as well as a special infrared «window» through Earth's atmosphere.

Science Interests Formation of galaxies and black holes in the early universe and their growth over cosmic time; large surveys with Hubble and other telescopes to discover new populations of distant galaxies and black holes; physical properties of active galactic nuclei using observations from radio, infrared, optical, ultraviolet through to X-ray energies.

Maintaining a normal body temperature (37 degrees C or 98.6 degrees F) involves two mechanisms: Energy production in your mitochondria from food, and photonic energy (near - infrared radiation from sunlight and incandescent light bulbs) that is able to penetrate deeply into your tissue, even through cloEnergy production in your mitochondria from food, and photonic energy (near - infrared radiation from sunlight and incandescent light bulbs) that is able to penetrate deeply into your tissue, even through cloenergy (near - infrared radiation from sunlight and incandescent light bulbs) that is able to penetrate deeply into your tissue, even through clothing.

The paper discusses many of the technical issues involved with the propagation of infrared thermal energy through the atmosphere.

Enough of this stupidity, this is the AGWSF Greenhouse Effect energy budget, that «shortwave heats the Earth and no longwave infrared from the Sun plays any part in heating the Earth's land and water», either because it doesn't get through some unknown unexplained silly idea of an invisible barrier like the glass of a greenhouse, as per Arrhenius's getting Fourier wrong, or, as Pekka gives, that the Sun produces very little longwave infrared.

Next: «Solar radiation at the frequencies of visible light largely passes through the atmosphere to warm the planetary surface, which then emits this energy at the lower frequencies of infrared thermal radiation.

They will perform CO2 tests, and use Infrared technology to determine if the house has energy leaks, specifically spotting drafty areas through windows and doors and there's a blow door blaster test included.

Since the infrared - inactive gases don't emit infrared light, if enough absorbed energy is transferred to the nitrogen and oxygen molecules through collisions, that could theoretically increase the average energy of the air molecules, i.e., it could «heat up» the air.

The light from the Sun passes through the Earth's atmosphere, which is transparent to visible light (that's why our eyes evolved to be sensitive to this kind of electromagnetic radiation), and warms the surface of the Earth, which in turn reradiates the energy, now as infrared radiation, because the Earth's surface isn't as hot as the Sun.

Because of its molecular structure, carbon dioxide is a greenhouse gas, which means it allows visible light from the Sun to pass through the atmosphere while absorbing and reemitting infrared energy, heating the Earth.

However, if even a small fraction of the latent heat is converted directly into infrared photons it changes the energy flow through the system; the Earth is cooled as IR generated in the atmosphere.

The scientists have developed a coating for solar panels that allows them to use the infrared portion of the light spectrum that usually passes right through solar cells without being converted into electricity, essentially wasted energy.

In 1996, Japanese scientists discovered A. marina living on the light left over by Chl a organisms and able to stretch into the far - red and near - infrared through the novel pigment Chl d instead of Chl a. Research at GISS has quantified the photon energy use efficiency of A. marina in comparison to Chl a organisms, and is now turned toward investigating its light regime in nature to ascertain its kinetics of light use and competitive ecological niche.
