Nanometer - A measure of distance usually used to measure wavelengths of light. A nanometer is equal to one billionth (10-9) of a meter.
Nanometer: Unit of measure that is one-billionth of a meter. A nanometer-sized particle is smaller than a living cell and can only be seen with the most powerful microscopes.
nanometer (nm): A unit of length equal to 10-9 m.
natural law: A conjecture about how nature works in which scientists have overwhelming confidence.

nm -- Nanometer (10-9 m).
nm -- Nautical Mile, equal to the distance spanned by one minute of arc in latitude, 1.852 km.
NMC -- Network Monitor and Control subsystem in DSN.
If red has a wavelength of 700 nanometers (one nanometer is one billionth of a meter) and green has a wavelength of 550 nanometers, then using the Doppler shift formula, what was his speed as a fraction of the speed of light c.
01 to 10 nanometers. X-ray astronomy dates to 1949 with the discovery that the sun emits X rays. Since X rays could not be observed from ground-based telescopes, V-2 rockets launched from White Sands, N.Mex.
The early spectra of Types Ib and Ic do not show lines of hydrogen nor the strong silicon absorption feature near 615 nanometers.
Such waves were visualized as analogous to those on the surface of water (transverse waves) but with an extremely short wavelength of about 500 nanometers (one nanometer is 10-9 meter).
The best UV light sources produce both long-wavelength (300-400 nanometer "black light") and short-wavelength (less than 300 nanometer) light.
Astronomers often use a unit called the nanometer (nm) when describing the wavelength of light (see Appendix 2). There are 109 nanometers in 1 meter. An older unit called the angstrom (1Å - 10 -10 m - 0.1 nm) is also widely used.
In the newer "SI" version of the metric system, we think of visible light in units of nanometers or 0.000000001 meters (10-9 m).
This view is a composite of images taken using filters sensitive to ultraviolet (centered at 338 nanometers), green (centered at 568 nanometers), and near-infrared (centered at 930 nanometers) light, ...
This composite of two mosaics was taken through the clear filter (610 nanometers) of the solid state imaging (CCD) system on November 9, 1996, during Galileo's third orbit of Jupiter. The ring was approximately 2,300,000 kilometers away.
0 nanometers produced by iron in the solar photosphere. The H-alpha telescope is sensitive to the spectral line at 656.3 nanometers, originating in the Sun's chromosphere, the layer of the solar atmosphere just above the photosphere.
This technique permits the formation of metal particles with particle sizes between less than 1 nanometer to 10 nanometers.
It is a false-colour, red-green-blue composite view generated from images taken through the Pancam's 750-nanometer, 530-nanometer and 430-nanometer filters.
The treatment apparently works even better if used with red visible light (660 nanometer) resulting in a 76% reduction of lesions after 3 months of daily treatment for 80% of the patients; ...

Angstrom, Å, is 0.1 nm. Angsrtoms have traditionally been used to describe wavelengths of light. The nanometer is generally preferred today.
The eye is sensitive to wavelengths ranging from deep violet 390 nanometers (nm) to 710nm (deep red). Maximum sensitivity is around 550nm at normal illumination. With decreasing light levels this sensitivity shifts toward the blue.
Light is measured by its wavelength (in nanometers) or frequency (in Hertz).
One wavelength
equals the distance between two successive wave crests or troughs.
Frequency (Hertz)
equals the number of waves that passes a given point per second.
The aluminum is vaporized in a vacuum, causing a film of metal, about 100 nanometers thick, to be deposited on the glass. Layers of other materials, such as silicon dioxide, may subsequently be laid down to give protection.
It also has a relatively flat electromagnetic spectrum in the visual region (wavelength range 350-850 nanometers, most of which can be seen with the human eye), so the flux densities are roughly equal, 2000-4000 Jy.
Visible light is that portion of the spectrum between the wavelengths of about 400 nanometers (abbreviated nm) and 800 nm (in air). Light can also be characterized by its frequency. The frequency and wavelength of light obey the relation ...
It is studying radiation with a wavelength of 0.21 meters. The Hubble is studying radiation at 500 nanometers (= 5 × 10-7 meters). What is the ratio of the Green Bank Telescope's resolution compared to the Hubble at their appropriate wavelengths?
It is able to study ice, soil, rock, and atmosphere using a microscopic imaging system capable of resolving materials down to 10 nanometers in size. That's 1,000 times smaller than the width of a human hair.
The wavelength of an AM radio wave is about 300 meters (one-fifth of a mile), while the X-rays emitted by a dentist's X-ray machine might have a wavelength of only a nanometer (one billionth of a meter).

Other types of optical filters use interference to produce very narrowband filters where the waveband may only be a few nanometers wide. One example is the H-$alpha filter that peaks at 652 nm. It is used for solar observations and .
