The Stefan-Boltzmann Apparatus is designed to experimentally verify the Stefan-Boltzmann law of radiation. It allows students to study radiative heat transfer, measure emissive power of surfaces, and understand the dependence of radiation on temperature.

Educational Objectives

• Understand the principles of thermal radiation.

• Verify the Stefan-Boltzmann law experimentally.

• Measure radiative heat flux from heated surfaces.

• Study the effect of surface temperature and emissivity on radiation.

• Compare experimental results with theoretical predictions.

Performance Measurement

• Measurement of surface temperature using thermocouples.

• Determination of radiative heat flux.

• Calculation of emissive power and radiation constants.

• Analysis of effect of emissivity on radiative heat transfer.

Panel and Instruments

• Radiating surface with controllable heating element.

• Thermocouples or temperature sensors with digital display.

• Radiation sensor or detector.

• Power supply with voltage and current measurement.

• Insulated test chamber with safety guard.

• Instructional panel with labeled components.
