Sentences with phrase «given wavelength»

Each of these particles — every quantum of light at a given wavelength — carried the same amount of energy, he argued, and so dispatched a single electron with the same energetic kick.

The «phase velocity» describes how fast waves of a given wavelength move, and the «group velocity» describes how fast the light conveys energy or information.

CHESS is equipped with what's known as a spectrograph, which can parse out just how much of any given wavelength of light is present.

Spectra provide information on how much of any given wavelength of light is present.

So looking at any given wavelength can give information about just one temperature of material at a time.

the simple thought experiment demonstrates completely and absolutely that (under these restrictive conditions) emissivity = absorptivity (at a given wavelength and direction).

This parameter emissivity is equal to the absorptivity or absorptance, of a body at any given wavelength — or across a range of wavelengths.

For example, at any given wavelength, absorptivity = emissivity.

At any given wavelength, the amount of light surviving goes down like the exponential of the number of molecules of CO2 encountered by the beam of light.
