012-04695D Thermal Radiation System
Questions (Part 1)
① List the surfaces of the Radiation Cube in order of the amount of radiation emitted. Is the order
independent of temperature?
② It is a general rule that good absorbers of radiation are also good emitters. Are your measure-
ments consistent with this rule? Explain.
Questions (Part 2)
① Do different objects, at approximately the same temperature, emit different amounts of radiation?
② Can you find materials in your room that block thermal radiation? Can you find materials that
don't block thermal radiation? (For example, do your clothes effectively block the thermal
radiation emitted from your body?)
Absorption and Transmission of Thermal Radiation
Questions
① What do your results suggest about the phenomenon of heat loss through windows?
② What do your results suggest about the Greenhouse Effect?
