Thermic

The emissivity of a hot objects produces infrared radiation which can be viewed in real time. By calibrating this radiation from known sources, it is then possible to make a temperature calibration.

Thanks to the infrared camera, the heat spread along a heated metal bar is recorded over time. This experiment allows to determine the thermal conductivity of different materials, and demonstrates that it is a propagating phenomenon related to internal movement of charge carriers. Lire la suite
