1. The problem statement, all variables and given/known data Use the Boltzmann distribution function to calculate the temperature at which 1.00% of a population of photons will have energy greater than 1.00 eV. The energy required to excite an atom is on the order of 1 eV. 3. The attempt at a solution I attached my attempt but it only solves for temperature at which 1% of photons are at 2eV. I have no idea to find temperature at which 1% of photons are greater than 1eV.
