Select Bohr model.

In the Help menu, select Transitions to see all possible transitions.

Move the Slow...Fast slider all the way over to Slow. Set the Light Controls to Monochromatic.

Set the light source to 103 nm. This provides photons of just the right energy to raise (excite) the electron from n=1 to n=3 shell (13 transition). online lab: https://phet.colorado.edu/sims/cheerpj/hydrogen-atom/latest/hydrogen-atom.html?simulation=hydrogen-atom
