2. Consider an electron in a hydrogen atom that is transitioning from the n = 2 to the n = 6 level. What is the wavelength (in nm) of the photon associated with this transition?

The electron in a hydrogen atom is in an energy state principal quantum number 9. The electron makes a transition to the energy state with principal quantum number 2 via an intermediate state principal quantum number 4. In making this transition two photons are emitted by the hydrogen atom. What is the sum of the wavelengths of these two photons? Give your answer in nm. nm

10. A singly ionized helium atom is in the ground state. It absorbs energy and makes a transition to the n = 3 excited state. The ion returns to the ground state by emitting three possible photons. What is the wavelength of the highest energy photon? 3 ƒ60 ssfo f60ª f60 ssf ) ssf60°
