An electron de-excites from the fourth quantum level to the third and then directly to the first. Two frequencies of light are emitted
How do their combined energies compare to the energy of the single frequency that would be emitted by de-excitation from the fourth level directly to the first level? Answer: The combined energies of the two frequencies emitted by the one electrons is A) greater than the energy of the single frequency. B) less than the energy of the single frequency. C) equal to the energy of the single frequency. D) not predictable because other factors, such as the temperature of the surroundings must also be considered.
