Hoe meet ik kleur temperatuur ?????????? is er een berekening voor of tabel tenopzichte van golflengte ????
There is a relationship between a colour temperature and the peak wavelength in its spectrum. It's called Wien's law.
Wavelength (nanometers) = 3,000,000 / Col temp (Kelvin).
So at 4,500K, the peak wavelength is 666nm (red) at 6,000K the peak wavelength is 500nm (bluish green) and at 7,500K the peak wavelength is 400nm (deep blue)
Outside these temperatures, the peak is outside the visible spectrum.
And in every case, that's just the peak wavelength - all other wavelengths are present as well, in slightly lesser intensities, adding up to a more-or-less white result.
