Sentences with phrase «scattered by the molecules»

That's why the researchers use a trick to study the molecules — they measure how strongly the X-ray light is scattered by the molecules.

UBC theoretical cosmology graduate student Elham Alipour, UBC physicist Kris Sigurdson and Ohio State University astrophysicist Christopher Hirata probed the effect of Rayleigh scattering — the process that makes the sky appear blue when the Sun's photons are scattered by molecules in the atmosphere — on the cosmic microwave background (CMB).

Some portion of this energy is reflected back into space by the Earth's atmosphere, another portion is dispersed and scattered by the molecules in the atmosphere and a large portion penetrates through the Earth's atmosphere to reach the surface of the Earth.

Not exact matches

The difference in the energy is determined by the properties of the molecules, and thus the scattered photons carry a unique fingerprint of the substance.

SERS is a surface - sensitive technique that enhances the inelastic scattering of photons by molecules adsorbed on rough metal surfaces or by nanostructures.

A technique to combine the ultrasensitivity of surface enhanced Raman scattering (SERS) with a slippery surface invented by Penn State researchers will make it feasible to detect single molecules of a number of chemical and biological species from gaseous, liquid or solid samples.

As target depth increases, the single - scattered signal (red) becomes negligibly small, because it is more likely that the waves will get bounced around by other biological molecules in their path (blue).

By the way, this effect is most prevalent when the particles that do the scattering are smaller than the wavelength of light, as is the case for the nitrogen and oxygen molecules in the atmosphere.

When a sample is excited by a laser pulse, most of the photons are scattered elastically, i.e., at the same frequency as the incident photons, by the molecules or atoms in the material.

By making the switch, all molecules made from fatty acids can be observed inside living cells by an advanced imaging technique called stimulated Raman scattering (SRS) microscopBy making the switch, all molecules made from fatty acids can be observed inside living cells by an advanced imaging technique called stimulated Raman scattering (SRS) microscopby an advanced imaging technique called stimulated Raman scattering (SRS) microscopy.

The new technique developed by Brasselet and her research team makes use of a nonlinear effect called coherent Raman scattering that occurs when light interacts with molecules.

He usually has to settle for the whisper of hydrogen and ammonia molecules, picked up by radio towers scattered across the world.

But as the sun edges toward the horizon, the light must travel increasingly longer paths and is scattered by more air molecules.

Their big, hanging ears also plays a major role in catching scents by preventing the wind from scattering away the scent molecules.

When sunlight passes through the atmosphere, the blue wavelengths are scattered more widely by the oxygen and nitrogen molecules, and more blue comes to our eyes.

Then recently I hear that, «no, N2 molecules by themselves» scatter most of the blue hues we see on a «clear» day.

Compare with electronic transition absorption of visible light by the electrons of the molecules of nitrogen and oxygen in the atmosphere, the real gas Air, which is what gives us our blue sky, reflection / scattering.

About half of the albedo comes from clouds, with the surface and Rayleigh scattering by atmospheric molecules contributing the rest.

Not being absorbed by real world water, visible is not only not capable because of its tiny scale of moving the whole molecule of water into vibration which is what it takes to heat water, but it isn't even able to be absorbed by the electrons of the water molecules as the electrons of the molecules of air absorb it, so water doesn't reflect / scatter visible light on the electrons of molecule level as does air, but gives up and passes it along, and so, visible is transmitted through, also, unchanged, but much delayed.

Visible light, however, is scattered in varying degrees by cloud droplets, air molecules, and dust particles.

The example I've given is of visible light in the atmosphere being bounced around the sky, actually reflected / scattered, by the electrons of the molecules of nitrogen and oxygen which comprise c98 % of our fluid gas atmosphere.

Because AGWSF fisics is fake there is no internal coherence in it, for example: if «all electromagnetic energy is the same and all creates heat when absorbed» then AGWSF fisics doesn't have any answer to the real world physics understanding of how visible light is reflected / scattered in the atmosphere which is by real technical absorption of visible light by the electrons of the molecules of nitrogen and oxygen, hence our blue sky.

Blue skies and red sunsets are in effect attributable to the preferential scattering of short (blue) wavelengths by air molecules and small dust particles.

The light is scattered by the atmospheric molecules and particles, and a fraction is collected back on the ground with a telescope.

Visible light gets absorbed by the electrons of the molecules of nitrogen and oxygen, and reflected / scattered by this.

I had earlier posted on refraction and reflection / scattering, what these mean, visible light gets reflected / scattered by being absorbed by the electrons of the molecules of nitrogen and oxygen in our real world atmosphere [it is therefore not «transparent» to visible as claimed in the TGE AGW energy budget..]

how does 6μ to 20μ wavelength of radiative heat energy being absorbed, scattered, diffused what ever mechanism you can invent, by 400 ppm volumetric density of CO2 with molecule size of 3.2 Angstrom, which means your purple ball size is ~ 1/3000 of your sun light yellow ball at atomspheric temperature of 15 C?

So during a high pressure, distant objects (mountains etc) appear more distant, with less visible definition to the details, and appear closer with greater visible detail pre a change in the weather (its very noticeable)... Is this the result of the SW light being scattered / or absorbed by the greater density o water molecules in the atmosphere during a high pressure system?

The problem of tracking rays layer by layer as gas molecules scattered or absorbed them was called «radiative transfer,» an elegant and difficult branch of theoretical physics.

Light waves can be reflected / scattered, absorbed, refracted, or transmitted to pass through matter unchanged and different materials will have different effects in these encounters; high energy light waves get scattered in our atmosphere from encounters with dust, water vapour, molecules, etc. as the white light hits the rough surface composed of these, so we have a blue sky for example, while the longer IR gets absorbed by water and earth, on a smooth surface such as glass or still water these high energy lights get reflected, angle of incidence equal to, and some pass through to get reflected or scattered at the next surface, think rainbow.
