Sentence examples for which wavelength from inspiring English sources

This renders the cells sensitive to light, allowing researchers to switch the cells on or off, depending on which Channelrhodopsin protein they express, and which wavelength of light is used.

A plasmon is a type of electrical wave, and a shell of a particular size will resonate with a plasmon of a particular frequency, rather as a bell of a particular size resonates with a particular note when struck.That is useful because an object's plasmon-resonance frequency governs many of its optical properties, including which wavelength of light it absorbs most easily.

In 1868 he published his great map of the solar spectrum in Recherches sur le spectre solaire ("Researches on the solar spectrum"), in which wavelength values were given in units of 10−10 metre, a unit that came to be called the angstrom.

It could be shown that light quality modulates vertical phytoplankton movement, but the empirical evidence as to which wavelength is responsible, was still lacking.

In the proposed laser source, a self-injection locked master FP-LD provides a stable continuous-wave (CW) lasing, which wavelength can be selected by means of an optical tunable bandpass filter (TBF).

Nevertheless, the part (which wavelength is longer than 1100 nm) of solar energy will be lost for that the Si semiconductor cannot absorb the energy below its band gap (1.12 eV).

The reflective properties of the surface of this object determine which wavelengths are absorbed and which are reflected, and this in turn determines the colour that the object appears.

Fourier-transform infra-red spectroscopy (FTIR) shines a beam of infra-red light on to a sample and then detects which wavelengths have been absorbed by various molecules.

By shining laser light onto hydrogen or antihydrogen and observing which wavelengths are absorbed, the energy levels of the two can be compared in detail.

They found that the size of the holes within the spongy layer, which are under genetic control, determined which wavelengths of light – and hence colour – were reflected and so seen by other birds or humans.

To improve the luminosity of a fluorescent converter for FNR, a novel type of converter was designed in which wavelength-shifting fibers were adopted to transport radiated light to the observation end face.
