In an Investigation of the Electronic Absorption Spectrum of a Particular

question 77

Multiple Choice

In an investigation of the electronic absorption spectrum of a particular element, it is found that a photon having $\lambda$ = 500 nm provides just enough energy to promote an electron from the second quantum level to the third. From this information, we can deduce

• A) the energy of the n = 2 level.
• B) the sum of the energies of the n = 2 and n = 3 levels.
• C) the difference between the energies of the n = 2 and n = 3 levels.
• D) the energy of the n = 3 level.
• E) all of these.
