The Balmer series describes emission of photons from a Hydrogen atom when an electron transitions to the first excited state (n=2) from a higher excited state. a) What would be the energy of the largest transition in this series? [1 mark] b) What would be the energy of the smallest transition in this series? [1 mark] c) What would be the frequency of the photons emitted by these transitions? [2 marks] d) How can knowing the frequency of these transitions help us find exoplanets? [2 marks]
