Donkeys, also called burros and asses, are found throughout the world. They look a lot like their cousins, but have long, floppy ears and tend to be stockier than horses or zebras. News
The above is not a true Color Temperature chart. Instead it is a hybrid, showing the color temperatures of light sources most commonly encountered in professional imaging. In our scale, tungsten-halogen has a color temperature of 3200Â°K. Household fluorescents are accepted to be around 4500Â°K, depending on the lamp. (They are shown for reference, but would not be part of a true Color Temperature chart, for reasons described below).
thin filament of the element tungsten (chemical symbol, W, for its old name wolfram). tungsten wire, so chosen because of its high melting point of 3410 oC. states release photons of a frequency that is visible to the human eye. incandescent light bulb is very weak in the 400 to 500 nm region(blue).
