Beschreibung:
In many light sources, for example, incandescent lamps or high-pressure gas-discharge lamps, a continuous light spectrum is generated by the interaction of large numbers of photons at very different energy levels. This means that the complete range of wavelengths is included, but in different proportions depending on the temperature.
Incidentally, the wavelength and energy distribution of incandescent lamps fit the Planck radiation formula extremely well.
Information and ideas:
Example of how physical laws are translated into technical applications. Double-coiled filaments are used, among other reasons, to increase the radiant surface.
