choose the atomic number of the atom, identify the element, and choose
which spectral lines to consider.
- Construct Your Own Problem
Consider the Doppler-shifted hydrogen spectrum received from a rapidly
receding galaxy. Construct a problem in which you calculate the energies
of selected spectral lines in the Balmer series and examine whether they
can be described with a formula like that in the equation
