I can know that some error was with straight line in result.
I can know that measuring efficiency enlarges as value great gradually.
DISCUSSION
We could confirm Stefan-Boltzmann law in black body radiation through this experiment. A black body radiation experiment did big part in development of modern physics enough to display boundary line of classical physics and modern physics.
We had not deduced exact value such as theoretical values in this experiment.
Like this, reason which some variation results is that black body that black body used in an experiment is ideal perfectly was not.
Theoretical black body is ideal black body verbatim. Actually, it is an ideal which is not exist. To feel experimenting have embodied perfect black body difficult.
Also, normal temperature is that is not kept changelessly. Actually, it is thought that there was change of temperature in normal temperature progressing an experiment about 1 hour 30 minutes, and because it don't have device that is kept indoor temperature as is fixed within a laboratory, I am thought that change of this normal temperature affected in result in some degree.
Although there was some error, we thought that had gotten result that approximate in some degree in result that had tried to get through an experiment and is thought that had gotten result that is worth can understand enough and forecast relation of temperature and energy in blackbody radiation.
CONCLUSION
We could confirm Stefan-Boltzmann law in black body radiation from experiment result. ( )
We think (according as Thermoelectric voltage increases) that this be proportional according as temperature increases before an experiment and predicted that the graph might appear straight.
That is, I can know that release energy of blackbody radiation is proportional to T4.
