Experiment: Stefan-Boltzmann law (115 V, 50/60 Hz)

Experiment: Stefan-Boltzmann law (115 V, 50/60 Hz), 8000692 [UE4050200-115], Intensity of Radiation
Product Inquiry
Objective: Verify that intensity of radiation is proportional to the fourth power of the temperature, T4


The way that intensity of radiation from a black body depends on temperature is described by the
Stefan-Boltzmann law. Similar dependence on temperature is exhibited by the intensity of radiation
from an incandescent lamp with a tungsten filament. In this experiment, a Moll thermopile is used to
make a relative measurement which verifies the law. The temperature of the filament can be determined
from the way its resistance depends on temperature, which can be determined very accurately
using a four-wire method.
