Zeeman effect: An atom in a state with its orbital quantum number l $=1$ decays to its ground state $($with l $=0).$ A photon of wavelength $630\mathrm{.}000$ nm is emitted in the process. When the same process takes place in the presence of an intense magnetic field, the following change in the spectrum is observed. With the magnetic field present, one of the emitted lines observed now has a wavelength of $630\mathrm{.}030$ nm$.$ Which of the following wavelengths would you expect to be also present?
