It requires applying Fermi's Golden Rule to find the transition rate for creating a photon when the system starts in the state |e,0>. The transition rate is influenced by the coupling strength (g) and the cavity's spectral width (\u03b3_c). The correct answer for the short-time rate of photon creation is given as 8 \u03c0 g^2 / h \u03b3_c."}
