What is the initial quantum number, n, of the transition that generates the photon with the shortest wavelength? (Again, restrict your attention to the four illustrated transitions.) What is that photon's energy (in ev)? ev What that photon's wavelength (in nm)? nm Finally, consider all transitions from n, > 2 that end at n, = 2 (in other words, the entire Balmer sequence, not limited to the four illustrated transitions). What is the shortest possible wavelength (in nm) for any photon picked from the Balmer series? nm

This system, while ocillating, lowers its energy by dropping down one quantum state (quantum number n decreases by 1). If the energy that the oscillator loses is carried off by a photon, what would be the wavelength of this photon? Give your answer in meters. The answer does not depend on the oscillator's initial quantum state. A br ear vni
