A hydrogen atom is in the ground state. It absorbs energy and makes a transition to the n=4 excited state. The atom returns to the ground state by emitting 2 photons: one in dropping to n=3 state, and 1 in further dropping to the ground state. What are the photon wavelengths of (a)the first and (b)the second transitions?

Problem 2. The electron in a hydrogen atom is excited from theground state to the n = 4 state by absorption of a photon.
A) What was the wavelength of the absorbed photon?
B) What wavelength photons might be emitted by the hydrogen atom asthe electron returns to the ground state?

Suppose two different hydrogen atoms, labeled A and B, have their electrons in state n = 4. Atom A emits light when its electron transitions directly from the n = 4 state to the n = 2 state. Atom B emits light twice, as its electron first transitions from the n = 4 state to the n = 3 state, then transitions from the n = 3 state to the n = 2 state. (a) Are the three wavelengths of light the same or different? (b) How does the energy of the photon from atom A compare to the total energy of the two photons from atom B?
