Based on Planck's law for the radiance of the Sun, assuming a temperature T of 5775K, create four plots, which show 1.) The spectral irradiance versus photon wavelength 2.) The spectral irradiance versus photon energy 3.) The photon flux versus photon wavelength 4.) The photon flux versus energy. You can convert the radiance of the object to the irradiance by multiplying the radiance by the steradian angle of the Sun's disc as it is observed on Earth. That value is 6.794e-5 sr. At the end of Task 1, you should have four plots that look similar to the ones on the PV Lighthouse web site: https://www2.pvlighthouse.com.au/resources/courses/altermatt/The%20Solar%20Spectrum/intensity %20or%20photon%20flux.aspx The axis labels should match the ones on PV Lighthouse, except that you should not convert the photon flux to mA/(cm*eV), but leave it as Number of photons/(smeV). I strongly recommend doing this in Python using numpy and matplotlib. An example code can be found on the following website: https://dpotovan.github.io/Chem324/python-intro.html#plotting-with- matplotlib
