B2 practical: Planck's law GeoGebra
In this exercise you will use Planck's law to plot the black body spectra for different temperatures then show how Wien's law gives the peak wavelength and that the total power radiated per unit area is proportional to T4 (Stefan Boltzmann's law). This worksheet assumes that you know the basic functions of GeoGebra. Note that Planck's law is not on the syllabus but it is interesting to see a bit of the theoretical...
