A fundamental problem in computer and communication networks is the wavelength assignment ( WA ) problem : given a set of routing paths on a network , assign wavelengths ( channels ) to the paths such that the paths with the same wavelength are edge-disjoint . Development of diode-pumped solid-state lasers has been driven by industrial and commercial applications requiring high power ( generally several watts ) in the green ( 532 or 523 nanometers ) and ultraviolet ( 355 or 349 nanometers , and the fourth harmonic at 266 nanometers ) wavelength ranges . In a subtractive color space , the pigments manipulate the wavelengths that our eyes see . This mode also resembles a midlatitude baroclinic wave train , but has a longer zonal wavelength . For this step one may think of the dispersion axis as `` x " and of the spatial ( or echelle order m ) axis as `` y. " The first of four steps in the NEWSIPS wavelength calibration procedure was interactive and consisted of running the IRAF routine ecidentify to map the positions of a set of lines to wavelengths for a reference WAVECAL echellogram . The planet itself shows few obvious features at these ultraviolet wavelengths , due to scattering of light by molecules of the gases high in the atmosphere . By varying the dimensions of the core and shell , they can create nanoshells that absorb or scatter light across a very large range of wavelengths , both visible and infrared . We can then work out how big a black hole we need for its Compton wavelength to equal its Schwarzschild radius ! Your prediction : Based on your observations , what do you predict you will observe if a source of waves move towards you : Will the wavelength of the waves appear shorter , longer , or the same as when the source is stationary ? Colors and sounds are reduced to wavelengths ; sensations of heat and cold are reduced to readings on a thermometer ; taste , smell , feel are ignored in precise formulations .
