An Electron in an Atom Initially Has an Energy 5

question 7

Multiple Choice

An electron in an atom initially has an energy 5.5 eV above the ground state energy. It drops to a state with energy 3.2 eV above the ground state energy and emits a photon in the process. The wave associated with the photon has a wavelength of:

• A) 5.4 *10 ^{- 7} m
• B) 3.0 *10 ^{- 7} m
• C) 1.7 *^{- 7} m
• D) 1.15 * 10 ^{- 7} m
• E) 1.0 *10 ^{- 7} m
