than that of microwave radiation.
Hard x-ray radiation is
light with a
wavelength in the range of picometers — much shorter
than the
wavelength of
visible light.
Normally
visible light could not pick out the lines because the spacing between them — 150 nanometers — is smaller
than the
light's
wavelength.
Doing the same thing for smaller
visible wavelengths is harder, because the metamaterial elements must be made smaller
than the
wavelength of the
light.
In 1873, German physicist Ernst Abbe deduced that conventional optical microscopes can not distinguish objects that are closer together
than about 200 nanometres — roughly half the shortest
wavelength of
visible light.

visible light — shorter
wavelengths than the near - infrared regime, where most earlier adaptive optics imaging was performed.
When the layers have thicknesses below the
wavelength of
visible light — 400 - 700 nanometers — they interact with its wave properties rather
than treating it as a straight ray.

than the
wavelength of
visible light, they develop unusual optical properties.
«Particles of any kind, even much smaller
than the
wavelength of
visible light, will, as a rule, make the sky brighter but at the expense of its purity of color,» Bohren says, noting that the effect is more pronounced when there is a high concentration of large aerosols.
Aerosols that are close in size or larger
than the
wavelengths of
visible light tend to scatter all colors indiscriminately, increasing the overall brightness of the sky but dampening color contrast.
Infrared
wavelengths are longer
than those of
visible light, so the optics don't have to be as precise.
With much shorter
wavelengths than photons of
visible light, electron beams can be used to observe objects hundreds of times smaller
than those that can be resolved with an optical microscope.

visible from the southern hemisphere for the first time at submillimetre
wavelengths — between infrared
light and radio waves — and in finer detail
than recent space - based surveys.
The longer
wavelength to be detected by ALMA's antennas means that although they are accurate to much less

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 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

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).»
