Q1:

The diagram shows the binding energy of each energy level of a hydrogen atom. If an electron is in the ground state, what frequency of photon must it absorb in order to move to the energy level ? Use a value of eV⋅s for the value of the Planck constant. Give your answer to 3 significant figures.

Q2:

The diagram shows the emission spectrum of hydrogen for the visible part of the electromagnetic spectrum. The table shows the binding energies for the different energy levels of a hydrogen atom.

Energy Level	1	2	3	4	5
Binding Energy (eV)

Between which two energy levels must an electron transition in order to produce the emission line marked on the diagram?

Q3:

The diagram shows four possible transitions that an electron can make between the energy levels of a hydrogen atom. What name is given to this series of transitions?
