Calculate the wave number corresponding to the most energetic spectral line

  1. Nov 1, 2012 #1
    Calculate the wave number corresponding to the most energetic spectral line in the Lyman series for the hydrogen atom.
    Express your answer to six significant figures and include the appropriate units.

    I use the formula:

    Because the question asks the most energetic one, so
    [wave number = Rydberg's constant/h/c]
    I got the answer10974214m-1
    But the answer is wrong.
    What's wrong with my calculation?

    What makes you think the answer is wrong?

    I did it in MasteringChemistry. It says the answer is wrong.

    If you are given Rydberg's constant with three significant figures, you can't give the answer with eight.

    Not that I am sure that's the problem, but it surely can be one.
