When it has all its receiver bands enabled, ALMA will capture radiation from space in longer wavelengths, from a few hundred micrometers to approximately 1 millimeter (close to one thousand times
longer than visible light waves).
The new instrument on the James Clerk Maxwell Telescope on Mauna Kea allows astronomers to map areas of the sky in wavelengths some 1,000 times
longer than visible light.
It is primarily used to study infrared rays — slightly
longer than visible light — from young stars and distant galaxies.
Through all these ups and downs, the essential mission of Spitzer remained constant: to learn more about the universe by detecting infrared rays, electromagnetic waves slightly
longer than visible light.
Not exact matches
And billions of years from now, if the universe continues to accelerate, distant galaxies will recede from us faster
than light and will no
longer be
visible.
It is also the brightest
light we have from the most distant (and oldest) stars because their otherwise -
visible light arrives stretched out to
longer, redder wavelengths by more
than 13 billion years of the universe's expansion.
After the serendipitous discovery of radio waves coming from the Milky Way's center in the 1930s, scientists realized radio waves, which have a
longer wavelength
than visible light, could reveal many aspects of cosmic phenomena not
visible in other wavelengths.
Infrared wavelengths are
longer than those of
visible light, so the optics don't have to be as precise.
Those unique properties have proven conducive to working with THz
light waves, which have
longer wavelengths
than visible light and therefore require new imaging technology.
Its energy has
longer wavelengths
than visible light.
The
longer wavelength to be detected by ALMA's antennas means that although they are accurate to much less
than the thickness of a single sheet of paper, the dishes do not need the mirror finish used for
visible -
light telescopes.
The best possible observations of the detached layer are made in ultraviolet
light because the small haze particles which populate this part of Titan's upper atmosphere scatter short wavelengths more efficiently
than longer visible or infrared wavelengths.
Infrared radiation is electromagnetic radiation of wavelengths
longer than the red end of
visible light and shorter
than microwaves, extending roughly from 1 micron (10 - 6 m) to 350 microns.
Different colors of
light correspond to different wavelengths, and invisible radiation has either
longer wavelengths (infra - red) or shorter wavelengths (ultra-violet)
than does
visible light.
The infrared spectrum: «Infrared (IR)
light is electromagnetic radiation with
longer wavelengths
than those of
visible light, extending from the nominal red edge of the
visible spectrum at 0.74 micrometres (µm) to 300 µm.»
Myrrh,
long before global warming was an issue I was taught that some colors were cooler
than others and that this was due to the amount of
visible light that was reflected.
Also you focused on re-radiating meaning emitting
long - wave spectrum - which possible, but I was thinking more about emitting the same wavelength, as mentioned in this quote: «However, aerosols (which often contain water and if so can absorb red wavelengths) are usually larger
than visible wavelengths and therefore absorb and reflect all wavelengths of
light equally (this is not technically scattering, although it is often called that; it technically involves absorption and re-radiation, or reflection).»
As we have discussed above, infrared radiation has a
longer wavelength
than visible light and can «go through haze more easily.
The
longer infrared rays are less energetic
than visible ones and do not slice through the atmosphere as easily as
visible light.
