Calculate the energy released for the transition from the first excited state, n=2, to the ground state, n=1, in hydrogen. State whether the energy is absorbed or emitted.
a) 4.34 times 10{-19} J, absorbed
b) 4.34 times 10{-19} J, emitted
c) 6.63 times 10{-34} J, absorbed
d) 6.63 times 10{-34} J, emitted
