Chapter 30, Problem 17

A wavelength of 486.2 nm is emitted by the hydrogen atoms in ahigh-voltage discharge tube. What are the (a) initial and (b) finalvalues of the quantum number n for the energy level transition thatproduces this wavelength?

For this question consider the figure to the right that shows an energy level diagram for a certain atom (not hydrogen). Several transitions are shown and labeled by letters. Note the diagram is not drawn to scale.

(A) Which transition corresponds to the emission of the photon with the longest wavelength?

(B) Which transition corresponds to the emission of the photon with the shortest wavelength?
