Sentences with phrase «energetic photons»

For the important ultraviolet photons which are desired to be removed from the solar radiation are those less energetic photons which decompose the ozone molecules to produce another oxygen atom which again can reform another ozone molecule.

This steps requires more energetic photons, which are known to be less numerous than less energetic photons.

The evidence for the long - held idea that processing of ices by energetic photons and cosmic rays produces complex molecules is weak.

In the past decade, research by Dwyer and others has shown that storms also produce positrons, as well as highly energetic photons, or γ - rays.

In the meantime, however, the exposed core becomes a violent scene of fusion reactions among remaining hydrogen and helium nuclei, which release a torrent of energetic photons, mostly in the form of ultraviolet rays.

Heisenberg and his fellow quantum pioneers recognized that very energetic photons will give a more accurate reading of the electron's position, but they are also more disruptive.

More important, a convergence of observations suggests that cosmic neutrinos spring from the same astrophysical sources as other particles from space: highly energetic photons called gamma rays, and mysterious ultra-high energy cosmic rays — protons and heavier atomic nuclei that reach energies a million times higher than humans have achieved with particle accelerators.

The radioactive decay of radon gas produces alpha particles (consisting of two protons and two neutrons, an alpha particle is just the bare nucleus of a helium atom), beta particles (which are actually fast - moving electrons), and gamma rays (very energetic photons).

Gamma - rays are extremely energetic photons and it takes a very violent event to produce them in large quantities.

Until recently, there hasn't been a method for producing a beam of such energetic photons.

The less energetic photon would then move on to a detector, and each diamond would be left either vibrating or not vibrating.

This higher state will usually be unstable and will revert to a ground state (for the surrounding conditions) typically by emission of a less energetic photon, plus heat.

Not exact matches

On Titan the photochemistry starts at the top of the atmosphere, about 1000 kilometres up, where energetic ultraviolet photons from the sun and cosmic rays trigger reactions among methane and nitrogen molecules.

To give the mirror the same kick a more energetic X-ray photon would produce, the light photons will have to reflect back and forth between two mirrors a million times.

The most energetic particles that strike us from space, which include neutrinos as well as gamma - ray photons and various other bits of subatomic shrapnel, are called cosmic rays.

The attached figure illustrates how energetic gamma rays (dashed lines) from a distant blazar strike photons of extragalactic background light (wavy lines) and produce pairs of electrons and positrons.

Consequently areas with a lot of photons and dark energy show up on scans as more energetic and hotter.

In 1912 it was shown that the much more penetrating gamma rays have all the properties of very energetic electromagnetic radiation, or photons.

Gamma - ray photons are between 10,000 and 10,000,000 times more energetic than the photons of visible light when they originate from radioactive atomic nuclei.

The atmosphere as a whole is more energetic and there are therefore more photons bouncing around — more escape directly to space balancing more or less the incoming radiation.

The infrared photons that dominate the downwelling spectrum are all individually less energetic than the heat of vaporization required.

To address these challenges, the Molecular and Nanoscale Interfaces Project aims to couple light absorbers, catalysts, and half - reactions for optimal control of the rate, yield, and energetics of electron and proton flow at the nanoscale, so that complete macroscale artificial photosynthetic systems can achieve maximum conversion of solar photon energy into the chemical energy of a fuel.

These models are based on the assumption that the particle's (atom, molecule, or cluster) transition from the higher energetic level (vapor or liquid) to a lower one (liquid or crystal) produces an emission of one or more photons.

Imagine instead of photons, or whatever your favorite energy metaphor, we are dealing with energetic particles.

Radiation from a molecule at -80 C therefore can not provide enough energy in the form of photons, to warm molecules (by boosting electrons into higher, more energetic orbits) at -4 C or above (seawater temperatures).
