Not exact matches

The Dalian Coherent Light Source, whose completion was announced today in Beijing, has a twist that makes it unique: It is the only large laser light source in the world dedicated to the particular range of short - wavelength light called vacuum ultraviolet, which makes it «a new tool for the detection and analysis of molecules undergoing chemical reactions,» says Alec Wodtke, a physical chemist at the Max Planck Institute for Biophysical Chemistry and the University of Göttingen in Germany..

This involves determining the composition of a planetary atmosphere by measuring its spectra, the distinctive radiation that gases absorb at their own particular wavelengths.

Since different elements and compounds absorb light at characteristic wavelengths, astronomers can determine what chemicals make up a planet's atmosphere by measuring the relative amounts of light that come in at particular wavelengths.

The possibility of such cells has been debated at least since the 1950s, when researchers found single neurons in the visual cortex of cats and other animals that respond to simple stimuli, such as lines oriented at a certain angle or moving in a specific direction, or light of a particular wavelength.

In their proof - of - principle experiment, the researchers used germanium antimony telluride (GST)-- the kind of phase - change material found in CDs and DVDs — to make an improved switchable metasurface that can block or transmit particular wavelengths of light at the command of light pulses.

Planets with atmospheres are able to warp starlight in another way: while the body of the planet blocks a big chunk of starlight as it crosses in front of its host star, the planet's thin, enveloping atmosphere absorbs starlight at particular colors, or wavelengths.

The SPT is designed to conduct low - noise, high - resolution surveys of the sky at millimeter (mm) and submillimeter (submm) wavelengths, with the particular design goal of making ultra-sensitive measurements of the cosmic microwave background (CMB).

The radio telescopes operated continuously at a wavelength of 10.7 centimetres, which is an ideal wavelength for monitoring solar activity due to the Sun's particular chemical composition.

That first quasar and others identified later puzzled astronomers because, when their light was analyzed to find the characteristic «signature» of emission at specific wavelengths shown by particular atoms, the pattern was at first indecipherable.

Each receiver type is sensitive to a particular «band», or range of wavelengths of the electromagnetic spectrum, and data can only be taken in one band at a time.

If you're not on the wavelength of Darren Aronofsky's particular artistic / environmentalist / religious anxieties, there's not much to recommend in this movie at all.

-- Matt Trask, a secondary senior physics teacher is having students make musical instruments to learn about wavelength — Kelly Skehill using design and software for students to apply calculus models to create new pop bottle designs — teachers are using technology to capture assessment information during the learning process — one particular good example at PJ Elementary — Kindergarten teacher (Sonia Southam) using iPads to engage parents and transform communication by capturing daily learning and sharing immediately via email with parents — the creation of Gleneagles Learning Lab Open House to showcase the process of learning — a teacher created Social Dynamics course for students with high functioning autism — the creation of an outdoor learning program for grades 6/7 students at Bowen Island Community School (Scott Slater created) that has students blending in - class and outdoor learning experiences

If there is a greater density of CO2 molecules, then the probability of a particular photon, at one of these wavelengths that CO2 absorbs, coming across a CO2 molecule, is clearly increased.

One can also refer to monochromatic (spectral) fluxes and intensities, which is the flux or intensity at a particular frequency ν (or wavelength λ, or photon energy E) per unit of the spectrum (per interval of ν or λ or E, or even per unit log (ν), etc.).

Microwave radiometry data are used to construct brightness temperatures: an indication of the intensity of electromagnetic energy at a particular wavelength that filters up through the atmosphere and reaches the satellite's sensor.

You could think about how a drop of dye in a tank full of water can give the whole water a tint which reduces its transparency at that particular wavelength.

(Note, by the way, that what is true for a radiating object is that the amount of radiation emitted AT ANY PARTICULAR WAVELENGTH is an increasing function of the temperature, a fact that is not always obvious because people often tend to normalize the emission curves when showing emission curves for different temperatures on the same graph.)

The heat we «feel» from the sun is about equal amounts of Vis and NIR, how much influence each has on a particular object depends on its absorbance at the particular wavelength, a black body will be heated by all wavelengths incident on it.
