An atomic lamp is often used as a calibration source for
spectrometers because the spectral emission lines are well defined
and spaced such that they are easy to identify. An electric current
is used to excite the valence electrons to excited states from
which they decay to the ground state emitting photons. For the
hydrogen atom, calculate the wavelength (in nm) of the first five
lines in increasing wavelength fpr nf=2, nf=3, nf=4, nf=5 and
nf=6
