Wavelengths

Some articles on wavelengths, wavelength:

Coded Aperture - Rationale
... Image formation, normally done at optical wavelengths by lenses and mirrors, must be done for non-focusable wavelengths via image modulation ... or reflecting telescope), and therefore is normally not favored at wavelengths where these techniques can be applied ...
Aery - Optical Properties - Absorption
... Different molecules absorb different wavelengths of radiation ... For example, O2 and O3 absorb almost all wavelengths shorter than 300 nanometers ... Water (H2O) absorbs many wavelengths above 700 nm ...
Strontium Aluminate
... The excitation wavelengths for strontium aluminate range from 200 to 450 nm ... The wavelength for its green formulation is 520 nm, its blue-green version emits at 505 nm, and the blue one emits at 490 nm ... Colors with longer wavelengths can be obtained from the strontium aluminate as well, though for the price of some loss of brightness ...
Mass Attenuation Coefficient - Calculating The Composition of A Solution
... or solvent, ideally across a broad spectrum of wavelengths, must be measured or looked up ... Remember, and each are functions of wavelength.) If there are N solutes or solvents, this procedure requires at least N measured wavelengths to create a solvable system of simultaneous equations ...
