A sankey diagram of energy losses in a fluorescent lamp a typical 100 watt tungsten filament incandescent lamp may convert only 5% of its power input to visible white light (400–700 nm wavelength), whereas typical fluorescent lamps convert about 22% of the power input to visible white light. Lighting wavelength diagrams. The frequency of wavelength range for indigo is around 425-450 nm and frequency of 670-700 thz in the above color spectrum chart, indigo is made a subset of violet color the low range of the color explains why it is difficult to distinguish this color in the spectral band.
lighting wavelength diagrams
The human eye sees color over wavelengths ranging roughly from 400 nanometers (violet) to 700 nanometers (red) light from 400–700 nanometers (nm) is called visible light, or the visible spectrum because humans can see itlight outside of this range may be visible to other organisms but cannot be perceived by the human eye. Electromagnetic spectrum, the entire distribution of electromagnetic radiation according to frequency or wavelength. although all electromagnetic waves travel at the speed of light in a vacuum, they do so at a wide range of frequencies, wavelengths, and photon energies..
