Sentences with phrase «emit ultraviolet wavelengths»

The solar blind camera takes images of objects that emit ultraviolet wavelengths.

Not exact matches

Some observations of how cosmic molecules emit and absorb light at ultraviolet wavelengths have hinted that the fine structure constant, responsible for the strength of electromagnetism, is not the same throughout the universe.

The problem with today's resist, however, is that it was originally developed for light sources that emit so - called deep ultraviolet light with wavelengths of 248 and 193 nanometers.

The «colours» are due to differences in the surface temperature of starsw1: hotter stars emit most of their light in the visible blue or ultraviolet regions of the electromagnetic spectrum, whereas cooler stars radiate at longer wavelengths, in the visible red or infrared regions (see Mignone & Barnes, 2011a).

When the star's ultraviolet radiation strikes the gases in the nebula, they heat up, giving out radiation ranging in wavelength from blue — emitted by hot oxygen in the bubble near the star — to yellow — emitted by hot hydrogen and nitrogen.

The distance to the quasar is so great (about 10 billion light - years) that the emitted light is «stretched» by the expansion of the universe from an invisible ultraviolet wavelength to a visible shade of violet by the time it reaches the 10 - meter Keck I telescope and the LRIS (Low Resolution Imaging Spectrometer) used for this discovery.

Although only 1 percent of the sun's energy is emitted at ultraviolet wavelengths between 200 and 300 nanometers, the decrease in this radiation from 1 July 1981 to 30 June 1985 accounted for 19 percent of the decrease in the total irradiance over the same period.»
