Calculate the frequency of light emitted by a hydrogen atom when an electron makes a transition from the fourth to the second principal quantum level.

I know that to solve this problem, we first use the empirical formula for a H-atom to solve for the energy of the electron in energy levels 4 and 2, then find change in energy for the electron, and lastly use E=hv to calculate the frequency of light emitted. However, I was wondering if instead of doing the steps above, we could just use the Rydberg equation to solve for the frequency of light emitted.
