Two energy levels of an atomic system are separated by energy correspo

Question

Two energy levels of an atomic system are separated by energy corresponding to frequency 3.0 × 10¹⁴ Hz. Assume 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 × 10⁻²³ JK⁻¹ and h = 6.6 × 10⁻³⁴ Js.

In an atomic system having only two energy levels, the population of atoms in each level at thermal equilibrium is governed by the Boltzmann distribution. The separation between the two energy levels is given in terms of the corresponding radiation frequency as 3.0 × 10¹⁴ Hz. The energy difference between the upper and lower levels is therefore obtained using the Planck relation ΔE = hν. Substituting the given ______ ________ _______ _____ _________.
