Blackbody Exponent and the vacuum Filament

The goal of this lab is (1) to test the T4 exponent behavior of blackbody radiation and (2) test the exponential suppression of the black body radation at wavelenghts shorter than the Wien maximum.
Setup the circuit as shown and do both parts!

Circuit to setup
Part 1: Measuring the exponent of the Stefan-Boltzmann law with a vacuum filament
Part 2: Frequency Windowed Photoemission from a vacuum filament.
