Solar heating

Solar heating

 

Objectives:

The objective of this experiment is to explore how insulation, covers and different surface materials effect the power and efficiency of a solar panel.

WILHELM CARL WERNER OTTO FRITZ FRANZ WIEN (1864-1928), German physicist who received the Nobel Prize for Physics in 1911 for his displacement law concerning the radiation emitted by the perfectly efficient blackbody (a surface that absorbs all radiant energy falling on it). Although the radiation emitted from a blackbody is distributed over a wide range of wavelengths, there is an intermediate wavelength at which the radiation reaches a maximum. In 1893 Wien stated in his law that this maximum wavelength is inversely proportional to the absolute temperature of the body. Because the accuracy of Wien's law declined for longer wavelengths, Max Planck was led to further investigations culminating in his quantum theory of radiation.  Wien also made contributions in the study of cathode rays (electron beams), X rays, and canal rays (positively charged atomic beams).

Materials:

Temperature sensor, CBL, TI83/84, solar heating panel, insulation material and plastic or glass covers.
