The PASCO Thermal Radiation System includes three
items: the TD-8553 Radiation Sensor, the TD-8554A
Radiation Cube (Leslie's Cube), and the TD-8555
Stefan-Boltzmann Lamp. This manual contains
operating instructions for each of these items plus
instructions and worksheets for the following four
experiments:
① Introduction to Thermal Radiation,
② Inverse Square Law,
③ Stefan-Boltzmann Law* (at high temperatures),
④ Stefan-Boltzmann Law* (at low temperatures).
* The Stefan-Boltzmann law states that the radiant
energy per unit area is proportional to the fourth
power of the temperature of the radiating surface
