A hydrogen atom is in the second excited state (n = 3). To what state %3D should it jump to emit light with the shortest possible wavelength, n = 1 n = 4 n = n = 2 Question 8 If you observe an emission spectrum with two lines, line A with 600 nm wavelength and line B with 300 nm wavelength, what can you say about the difference between the electron transitions emitting those two lines? Line B transitions have twice the energy of Line A transitions Line A trancitions haye twice th onerg of Line R trancition
