The energy emitted by a photon when it falls from level f to energy level b is 2.84 eV.
Energy of photon at level f and level b
The energy of a photon at level F is given as -268 eV and the energy photon at level b is given as -5.52 eV.
Energy emitted by a photon when it falls from level f to energy level b is calculated as follows;
ΔE = -2.68 eV - (-5.52 eV)
ΔE = -2.68 eV + 5.52 eV
ΔE = 2.84 eV
Thus, the energy emitted by a photon when it falls from level f to energy level b is 2.84 eV.
