# Use Planck’s radiation law to derive the Stefan-Boltzmann

## Homework Statement

a) Use Planck’s radiation law to derive the Stefan-Boltzmann law for the case of zero background
temperature (i.e., T0 = 0).

Well, what do you think ALL possible wavelengths means? What is the shortest possible wavelength? (Hint: it can be made arbitrarily short). What is the longest possible wavelength? (Hint: it can be made arbitrarily long).
