Solving a problem in physics section 43 point 3 quantu

3. At the grating period d is normally incident beam of light from the discharge tube filled with atomic hydrogen. It was found that the spectrum of diffraction maximum k-th order, observed at an angle φ, match one of the lines of the Lyman series. Identify the principal quantum number corresponding to the energy level at which there was a transition.
