This essay is an examination of how the power of visible radiation depends on the temperature. An experiment was carried out to measure the relationship between the temperature and the emitted radiant power of incandescent tungsten. The experiment enables me to collect data to reach a conclusion between these two variables. Also, bearing in mind that resistor does not obey ohm’s law generally, due to the change of temperature, it is investigated that if the total emitted power would be changed due to this effect. A system was set up to collect data and a “TI-84 Plus” Graphic Display Calculator was used to calculate quantitative values obtained from the experiment. Also a computer programme (Logger Pro 3.8) was used to plot graphs which are derived from the data and calculations of the experiment. As a result of the experiment I found that there is a direct correlation between the emitted radiant power and temperature. The results were compared with the law governing the radiant power of an ideal black body, which is called Stefan-Boltzmann Law, to obtain the accuracy of the experimental values. Finally, I evaluated the sources of error and offered reasonable improvements for the experiment.
