Question

Two energy levels of an atomic system are separated by energy corresponding to frequency 3.0\times10^{14} Hz. Assuming that all atoms are in one or the other of these two energy levels, compute the fraction of atoms in the upper energy level at temperature 400 K. Take k_B=1.38\times10^{23}JK^{34} and h=6.6\times 10^{-34}Js

To find the fraction of atoms in the upper energy level at a given temperature, we can use the Boltzmann distribution, which states that the ratio of atoms in two different energy levels is given by:

\[ \frac{N_2}{N_1} = e^{-\frac{\Delta E}{k_B T}} \]
