Wavelength creates Color objects given the wavelength orthe frequency of the light rather than the usual RGB or HSB.instead of:Color c = new Color(255, 0, 0);use the frequency in nanometers, and gamma 0.0. .. 1.0.(gamma is intensity/brightness.)Color c = Wavelength.wvColor( 400.0f, 0.80f );The visible range of the spectrum is 380..780 nanometers.Smaller is bluer.or using frequency in Terahertz and gamma 0.0. .. 1.0.Color c = Wavelength.fColor( 500.0f, 1.0f );The visible range of the spectrum is 384..789 TeraHertz.Smaller is redder.Wavelength does not do much on its own. It is intended to beincorporated into your own programs.You might use it to draw a realistic rainbow, or to writeeducational Applets about the light spectrum.
