For a hydrogen-like atom, classify these electron transitions by whether they result in the absorption or emission of light.
n=3 to n=5, n=1 to n=3, n=3 to n=2, n=2 to n=1
Energy must be absorbed to for the electron to transfer from
ground state to a much higher energy level. In the same manner, Energy is
emitted when the electron is transferred from a higher energy level to a lower
energy level. Thus,
