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). |
