The gamma spectrum is characteristic of the gamma-emitting nuclides contained in the source, just as in optical spectroscopy, the optical spectrum is characteristic of the material contained in a sample.

The input to an optical spectrum analyzer may be simply via an aperture in the instrument's case, an optical fiber or an optical connector to which a fiber-optic cable can be attached.
33.
Each of the 2 GMOS instruments are currently having their detectors upgraded to Hamamatsu arrays, which will have significantly improved performance in the far red part of the optical spectrum ( 700 1, 000 nm ).
34.
The names of most of the colors were taken from the conventional colors of the rainbow or optical spectrum, and in the electronic color code, which uses the same 10 colors ( though in a different order ).
35.
NGC 4698 is classified as a Seyfert-2 galaxy with an active galactic nucleus, which displays a prominent emission of radio and X-ray energy from the core while showing narrow emission lines in the optical spectrum.
36.
The frequency response of optical spectrum analyzers tends to be relatively limited, e . g . ( near-infrared ), depending on the intended purpose, although ( somewhat ) wider-bandwidth general purpose instruments are available.
37.
Chromatic aberration manifests itself as " fringes " of color along boundaries that separate dark and bright parts of the image, because each color in the optical spectrum cannot be focused at a single common point on the optical axis.
38.
A source radiating a power of one watt of light in the color for which the eye is most efficient ( a wavelength of 555 nm, in the green region of the optical spectrum ) has luminous flux of 683 lumens.
39.
It seems to me that if magnetism and electromagnetism as also and magnetic and electromagnetic induction has optical spectrums, so that they may be has optical focuses .-- talk ) 15 : 32, 26 September 2016 ( UTC)

Isaac Newton included blue as one of the seven colours in his first description the visible spectrum, He chose seven colours because that was the number of notes in the musical scale, which he believed was related to the optical spectrum.
