Problem 50088.
When measuring the temperature of a hot tungsten filament, the radiation pyrometer shows a temperature Tp = 2000 K. Assuming that the absorptivity for tungsten does not depend on the radiation frequency and is equal to 0.35, determine the true temperature T of the tungsten filament.
A detailed solution with a brief note of the conditions, formulas and laws used in the solution, the derivation of the calculation formula and the answer.
