Lyman series for H

The Lyman series in the hydrogen atom corresponds to transitions that originate from the n=1 level in absorption or that terminate in the n=1 level for emission. Calculate the energy, frequency (in inverse seconds and inverse centimeters), and wavelength of the least and most energetic transition in this series.
